The pendular spectra of linear (HCCCN)(n) (n = 1-3) molecules were calculated under various rotational temperatures and electric field strengths. The normalized Q-branch intensity and its gradient were investigated. The study analyzed the range and sensitivity of measuring electric field strength with these molecules and proposed a high sensitivity scheme.
The pendular spectra of linear (HCCCN)(n) (n = 1-3) molecules at several rotational temperatures under a certain range of electric field strength E are calculated using the finite element matrix diagonalization method. In addition, the normalized Q-branch intensity (I-Q) and the gradient (K-E) of I-Q under corresponding conditions are investigated. Based on the results, the range and sensitivity of measuring the electric field strength with linear (HCCCN)(n) (n =1 - 3) molecules are analyzed. A scheme to measure electric field strength based on (HCCCN)(n) (n =1 - 3) with high sensitivity is proposed and the spatial resolution is also discussed. The feasibility of measuring the electric field strength of the electrostatic Stark decelerator based on a pendular spectrum is studied. (C) 2021 Optical Society of America
