Laser photofragmentation TOF mass

Because of the rapid dissociation of vibrationally excited HS radicals in the state, the determination of the HS(Z) vibrational distribution has not been made by the LIF method [128], Previous laser photofragmentation TOF mass spectrometric [129,131,132] and Doppler spectroscopic [130] experiments indicate that HS(X) formed by process 42 is vibrationally excited, up to v = 6, with the HS vibrational distribution peaked strongly at V = 0. Recently, Continetti et al. [132] have observed the 193-nm photodissociation of HS(X, v) (process 43) formed in process 42 at high photodissociation laser powers ... 

The first direct examination of primary photoproducts of thiophene at 193 nm has been made in a recent laser photofragmentation TOF mass spectrometric experiment [175], In this experiment, six product channels were identified, as summarized by processes 70-75 in decreasing order of importance ... 

The pioneering work of Wilson and co-workers [71-75] established cross-ed-laser and molecular-beam photofragmentation spectroscopy with time-of-flight (TOF) mass-spectrometric detection as a universal and detailed...
