Abstract
In this paper, we investigate the rotationally resolved spectra of hot CF radicals generated after IR multiphoton dissociation (IRMPD) of CF Cl3 or CF2Cl2 and subsequent UV photodissociation. It is shown that th ese conditions are advantageous for the spectroscopy of transitions in volving high rotational quantum numbers and hot bands. Thus molecular constants of CF for the first vibrationally excited state of the elect ronic ground state (A(v) = 77.1 cm-1, B(v) = 1.389 cm-1, D(v) = 6.570 X 10(-6) cm-1) are determined for the first time or are calculated mor e accurately. The spectroscopic method used was resonance-enhanced mul tiphoton ionization (REMPI) spectroscopy.
