Paper Abstract

Matrix studies featuring the FTIR instrumental advantages of resolution and sensitivity for a finite amount of time will be described. Ammonia clusters have a complicated spectrum in the N-H stretching region. One antisymmetric and two symmetric stretching modes in the dimer verify an asymmetric cyclic dimer structure.' Chlorine isotopic splittings have been resolved for the four H/D substituted (HC1)3 species, which confirm the cluster stoichiometry and triangular structure.2 The ammonia/hydrogen cyanide system reveals 1:1 and 1:2 complexes, which are identified from their FTIR spectra and characterized by comparison to similar complexes.3 The ozone/hydrogen fluoride system gives the 03--HF complex, and mixed oxygen isotopic spectra show inequivalent terminal oxygen atoms.4 The symmetrical PH3--03 complex photolyses to give an asymmetric HOP02 species based on mixed isotopic spectra.5
