Rotationally resolved spectra of the CaH radical using a supersonic molecular beam are reported. Thus, high energy resolution of the (1 + 1 ) REMPI spectra corresponding to the A β X and B β X electronic transitions were measured which allowed for the first time a clear and precise analysis of the l

β¦ Synopsis
Electronically excited states of CF31 have been investigated using resonance-enhanced multi-photon ionization. The electronic C band was examined by tuning the laser wavelength from 340 to 355 nm. Vibrational modes (u~. u2, v3) in this band werc observed and their band origin was measured. The experiments were performed both in a thermal gas of pure CF31 and in a supersonic molecular beam in order to reduce the hot bands.
