A critical investigation on the structure, electronic properties and optical activities of a series of transition metal doped porphyrins (TMP; TM = Fe, Co, Ni) in the light of infrared and Raman spectroscopy is performed, under density functional formalism. The structure and electronic properties are studied in terms of ionization potential, electron affinity, chemical hardness (eta), binding energies of the transition metals (BETM) etc. The origin of the optical activities, especially the visibly active cobalt porphyrin is addressed through critical study on their infrared and Raman spectra. The information availed from the spectral analysis will certainly ease their possible synthesis and useful applications in the sensor and optoelectronic domains. (C) 2017 Elsevier B.V.
