The line shapes of the Balmer lines ( n = 3, 4) produced from the reaction between methylene chloride and metastable helium atom He (2 3 S) in a high vacuum chamber were analyzed, and the nascent translational energies were estimated from the Doppler

A comparative spectroscopic study in the visible and ultraviolet ranges was conducted on the flowing afterglows resulting from the reactions of He(2 3S) and Ne(3P0,2) metastables with CS2. Penning ionization was found to be the predominant energy tra

A 1H dnmr study has been performed on a series of addition compounds formed from the gaseous reactions of di- and trimethyl amine and triethyl amine with sulfur dioxide in the presence of a small amount of water in a liquid sulfur dioxide solvent. Th

The energy transfer reation of He(23S) + CS was studied spectroscopically in a flowing afterglow apparatus. The CS+(B2Σ+ → A 2Πi) transition is identified via three members of the Δν = 0 sequence (406–415 nm). The spin-orbit splitting of the

The N/sub 2/(B/sup 3/II/sub g/) product-state distribution for v' = 0-12 has been analyzed from the fluorescence observed in an Ar(/sup 3/P/sub 2,0/) + N/sub 2/O afterglow. This vibronic distribution shows a non-Boltzmann property, inverted at v' = 4

A collinear model for predissociation of linear triatomic molecules is presented. A very steep repulsive potential for CS (A) + S is obtained by fitting the experimental results from the dissociation of CS2 at various excitation energies. Qualitative

The energy transfer reactions He(2 3 S) + H 2 O and He(2 3 S) + H 2 S were studied spectroscopically in the visible and ultraviolet ranges in a flowing afterglow apparatus. No primary triatomic ion emission was observed in this study. Only dissociati

The emission systems produced in He(2 3 S)/SO 2 , Ne( 3 P 0,2 )/SO 2 and Ar( 3 P 0,2 )/SO 2 , afterglows have been investigated in the ultraviolet and visible spectral ranges. In all three afterglows we have identified previously unknown long—wavel

Irradiation of n‐alkane solutions of all‐trans octatetraene at temperatures below 10 K produces a number of photoproducts. This paper reports spectroscopic and thermodynamic properties of one of these which has been identified to be the all‐tra

[Formula: see text] fluorescence emission was observed and analyzed in the 300–550 nm spectral range from a flowing afterglow study of the reaction He(23S) + SO2. The band system, which has its origin at 333.9 nm, is characterized by a long progres
