Book Description
Work on sub-Doppler spectroscopy of thioformaldehyde is nearing completion; the sub-Doppler structure in the H2CS spectrum correlates with previous observations of anomalously long fluorescence lifetimes and reduced quantum yields of fluorescence under collision-free conditions. Singlet-triplet perturbations are large and occur haphazardly when levels in the two states are near- coincidence. High-resolution FTIR spectra of many bands of HCOCl and DCOCl have been recorded. Laser fluorescence on formic acid is being studied. Reactive jet spectroscopy is being used to produce new reactive intermediates in F2/Ar gas streams. Preliminary experiments are underway in S3 and S4 systems.

Book Description
Work was done on sub-Doppler spectroscopy of thioformaldehyde, electronic spectrum of FS2 radical, FTIR spectra of the transient molecule formyl chloride (HCOCl and DCOCl), and high-resolution FTIR spectra of the?9 (CH2 wag) and?5 (CSO symm. stretch) bands of sulfine (H2CSO), a transient species formed in pyrolysis of dimethyl sulfoxide and oxidation of thioformaldehyde.

Book Description
This research concerns the study of the spectroscopy and excited state dynamics of a number of transient molecules containing either sulfur or oxygen. The identification and study of sulfur species which are analogs of important oxygen-containing combustion intermediates is important to our understanding of reactive intermediates. The oxygen-containing species chosen for study are new systems whose electronic spectra have not previously been identified. The major experimental technique used in this work was pyrolysis jet spectroscopy. Since many of the species have not been previously studied by laser techniques, much effort was devoted to determining methods for producing and observing them. We have been very successful in a number of cases and have developed some further experimental techniques.
