Abstract
AbstractGas phase emission and laser excitation spectra of the Ã2E↔X̃2E (Σ = +½, −½) transition of rotationally/vibrationally cooled 1‐chloro‐ and 1‐bromo‐1,3‐pentadiyne cations have been obtained. The emission was excited by electron impact on a seeded helium supersonic free jet and the fluorescence by laser excitation of cations produced by Penning ionization and collisional relaxation. From these two sets of data the origin bands of the spin‐orbit systems are located and for the bromo species this leads to better values of the spin‐orbit splitttings in the two electronic states and of the first adiabatic ionization energy. The vibrational frequencies of many of the fundamentals of these cations in the X̃2E and Ã2E states have been obtained to within ±2 cm−1.
