Gas phase protonated nicotine is a mixture of pyridine- and pyrrolidine-protonated conformers: implications for its native structure in the nicotinic acetylcholine receptor

Naoya Takeda et al.

Summary: The gas phase protonated nicotine exhibits two protomers, pyridine and pyrrolidine, with varying relative populations depending on the thermalizing trap temperature. The combination of IR spectroscopy and electronic structure calculations reveals a small energy difference between the two protomers, and one of the pyrrolidine protomers closely resembles the X-ray structure of nicotine in the nicotinic acetylcholine receptor (nAChR).

Controlled ultrafast ππ-πσ dynamics in tryptophan-based peptides with tailored micro-environment

Marius Herve et al.

Summary: Researchers combined an electron spray source with ultrafast pump-probe UV-Vis spectroscopy to study pi pi*-pi sigma* coupling in tryptophan-based ions and used mass spectrometry to produce isolated molecular ions with a controlled micro-environment. They measured ultrafast photo-induced pi pi*-pi sigma* dynamics in tryptophan species in the presence of a single, charged adduct, observing a significant increase in timescale when changing the added adduct atom. A model was proposed to rationalize the results based on the effects of the adduct on the electronic structure of the molecule, offering perspectives on controlling ultrafast molecular processes by designing the micro-environment on the Angstrom length scale.

Experimental Confirmation of a Topological Isomer of the Ubiquitous Au25(SR)18 Cluster in the Gas Phase

Elina Kalenius et al.

Summary: High-resolution electrospray ionization ion mobility mass spectrometry has identified a gas-phase isomer of the well-studied Au-25(SR)(18) cluster, with relative abundance controlled by in-source activation. The measured properties of the new isomer match theoretical predictions closely, suggesting that structural dynamics play a role in gas-phase reactions of thiolate-protected gold clusters and that isomerization may be manipulated by external stimuli.

Picosecond excited-state lifetimes of protonated indazole and benzimidazole: The role of the N-N bond

Samuel J. P. Marlton et al.

Summary: This study investigates the role of a protonated N-N chemical group in the excited-state deactivation of protonated indazole compared to its isomer protonated benzimidazole. Protonated indazole exhibits shorter lifetimes attributed to pi sigma* state mediated elongation of the protonated N-N bond, as determined by experimental results, quantum chemical calculations, and potential energy surfaces.

Quantification of monosaccharide enantiomers using optical properties of hydrogen-bonded tryptophan

Hiromori Murashima et al.

Summary: The study investigated chiral recognition between amino acids and monosaccharides in the gas phase as a model for chemical evolution in interstellar molecular clouds. Results showed that the optical properties of Trp in the clusters induced by 285-nm photoexcitation were useful for identifying and quantifying pentose enantiomers. Additionally, pentose enantiomeric excess in solution could be determined from relative abundances observed in a single product ion spectrum of 285-nm photoexcited hydrogen-bonded clusters of H+(L-Trp) and pentose.

Gas phase structure and fragmentation of [Cytosine-Guanine]Ag+ complex studied by mass-resolved IRMPD spectroscopy

Andres F. Cruz-Ortiz et al.

Summary: The silver-mediated cytosine-guanine [CGAg](+) pair was characterized by mass-resolved IRMPD spectroscopy and electronic structure calculations at the DFT level. Two isomers of the [CGAg](+) complex were identified based on the mass-resolved IRMPD spectra recorded on the mass of each fragment. The yields of each fragment are strongly dependent on the isomer of the precursor ion due to the fragmentation energy of the different channels.

Relative Energetics of the Gas Phase Protomers of p-Aminobenzoic Acid and the Effect of Protonation Site on Fragmentation

Maria Demireva et al.

Summary: Guided ion beam tandem mass spectrometry (GIBMS) was used to study the energy-dependent threshold collision-induced dissociation (TCID) of two protonated isomers (protomers) of p-aminobenzoic acid (p-ABA). Differences between the protomers were clearly distinguished through fragmentation channels, product abundance, and identity observed. The results show that the relative stabilities of the two p-ABA protomers can be directly determined from experimental data and are nearly isoenergetic in the gas phase.

Summary: Two ion populations of protonated Rivaroxaban are separated using differential mobility spectrometry under different conditions, showing similarities in CID behavior but distinct prototropic isomers based on UVPD spectra. The populations are attributed to bare protonated Rivaroxaban and to complexes with ammonia or acetonitrile, which dissociate prior to mass selection. Comparisons with computed spectra suggest proton sharing between distal oxygen centers in the identified prototropic isomers.

Electronic spectroscopy of differential mobility-selected prototropic isomers of protonated para-aminobenzoic acid

Neville J. A. Coughlan et al.

Summary: PABA was electrosprayed from mixtures of protic and aprotic solvents, resulting in the formation of two prototropic isomers in the gas phase, with their relative populations depending on the composition of the electrospray solvent. Differential mobility spectrometry (DMS) was used to separate the two ion populations in the gas phase, showing that the N-protonated isomer had a more negative CV shift than the O-protonated isomer. The study also demonstrated that CCSD vertical excitation energies and vertical gradient Franck-Condon simulations provided near-quantitative agreement with the measured spectral features, supporting the spectral assignments.

Investigating the mapping of chromophore excitations onto the electron detachment spectrum: photodissociation spectroscopy of iodide ion-thiouracil clusters

Kelechi O. Uleanya et al.

Summary: Laser photodissociation spectroscopy has been used to study the excited states and intracluster electron transfer in iodide complexes of non-native nucleobases with different sulfur atom substitutions. While photodepletion of I·4-TU and I·2,4-TU leads to the formation of the respective molecular anions, this behavior is not observed for I·2-TU. The spectral profiles of the clusters are largely determined by the nucleobase chromophore excitations.
