Study of small benzene clusters by pulse molecular beam mass spectrometry

摘要

A simple method for separating contributions of different-sized clusters formed in a pulse supersonic boum to a mass-spectral signal has been suggested. The method is based on the analysis of time pulse profiles measured for different ions of the beam and makes it possible to calculate mass spectra of small clusters. The electron impact mass spectrum of the benzene dimer has been obtained and analyzed in We framework of the concept of intracluster ion-molecular chemistry.
