More Book Details

Description of the Book:

Direct absorption IR laser methods developed under AFOSR support have been used to study state-to-state reactive scattering dynamics under single collision conditions. Efforts over this past granting period have led to significant progress in several areas: i) H atom abstraction dynamics in prototypic atom + diatom (e.g. X + HD — Hx(v,J) + atom + triatom (e.g. X + H2O — Hx(v,J) + OH(v,N)) and atom + polyatom (e.g. X + CH3-CH3) reaction systems, ii) application of novel slit discharge concentration modulation methods for ultrasensitive IR laser based detection of cold ions in supersonic jets, iii) stereodynamics of aligned collisions in rovibrationally state-selected molecules in crossed jets, iv) development of high sensitivity IR absorption methods to hyperthermal inelastic and reactive scattering at the gas-liquid interface, which indicate the presence of surprisingly hot, highly non-statistical product state distributions as well as direct evidence for both direct and trapping/desorption reaction channels
