A new electronic transition of the PCl molecule
Autor: G Tai, R D Verma
Publikováno v: Journal of Physics B: Atomic, Molecular and Optical Physics. 29:1381-1384
An electronic transition of the BN molecule has been identified from an absorption spectrum obtained by the flash discharge technique in the region 1860-1950 AA. From the vibrational analysis of the spectrum five bands at 1868.38, 1871.26, 1902.83, 1

ChemInform Abstract: Diphosphonium Fluorosulfonate Reagent as a Dehydrating Agent in Organic Synthesis
Autor: Debyani G. Niyogi, R. D. Verma, Sandeep Singh
Publikováno v: ChemInform. 26
A facile, one-pot dehydration of organic substrates is afforded by the ‘diphosphonium fluorosulfonate’ reagent, Ph 3 P + OP + Ph 3 ·2SO 3 F − . This reagent has been used to convert acids to anhydrides, acid and alcohols to esters, acids and a
