| Photodissociation experiments on expansion cooled bromine chloride (BrCl) and nitrosyl bromide (BrNO) were conducted using a pump/probe scheme. Resonance-enhanced-multiphoton-ionization (REMPI) spectroscopy allowed for state selective ionization of the photofragments. Using time-of-flight mass spectrometry (TOF-MS), it was possible to make use of the E-;Photodissociation experiments on BrCl were carried out at six wavelengths between 500 nm and 389 nm. These experiments established the Br*;The UV-Vis absorption spectrum of BrNO was recorded. At ten wavelengths between 740 nm and 225 nm photodissociation experiments were carried out. Guided by comparison with the well-studied ClNO dissociation dynamics, we propose the BrNO frontier orbitals and assign the absorption bands to the various low lying electronic transitions. The absorption from 740 nm to 370 nm is dominated by transitions to triplet states, which borrow intensity from the higher energy singlet state, S;Following excitation at 355 nm a narrow oscillation of the spatial distribution from a cos... |
