The optical absorption spectrum of gaseous NCl3 was measured from 170 to 350 nm, and experiments were performed in which this molecule was irradiated with a pulsed laser at 193 nm and 249 nm. Photo...

A number of experiments have been performed in an effort to better understand the photoinitiated chain decomposition of ClN3. Discharge-flow methods were used to determine the rate of energy exchange between vibrationally excited N2 (a likely chain c

Boron nitride (BN) thin films are deposited via the dissociation of B(N3)3 in a stream of excited N2. Experiments suggest the energy carrier responsible for dissociation of the azide is electronically excited N2(A3Σu+). Films grown on silicon and sa

Al(N3)3 is produced by the stoichiometric reaction between Al(CH3)3 and excess HN3 at room temperature. The reaction is thought to proceed by the addition of HN3 to Al(CH3)3 followed by elimination of CH4, repeated three times to produce the fully az

Time‐resolved laser‐induced fluorescence measurements indicate that Zn atoms excited to the 4 3PJ metastable state react rapidly with group‐VI molecules O2, CS2, and H2S. Rate constants for these processes are presented. Based on these data, a

The primary and secondary reactions in the H+NFCl 2 system have been studied by infrared chemiluminescence in a fast flow reactor at 300 K. The primary reaction is exclusively Cl atom abstraction to give HCl(υ=0-4) +NFCl with a total rate constant o

The reaction of NH(a1Δ) with Cl2 was studied by pulsed photolysis of HN3/Cl2/Ar mixtures with the 248 nm output of a KrF laser. The rate constant for NH(a1Δ) quenching by Cl2 was determined to be (6.8±0.4) × 10−11 cm3 s−1. A major product cha

The reaction of excess hydrogen or deuterium atoms with NCl 3 in a transverse flow reactor is used to generate NCl(a 1 Δ) at densities up to 10 13 cm −3 . The NCl a→X emission scales linearly with the NCl 3 flow rate over the entire range of rea
