✦ Synopsis
A low-pressure, low-energy charge-exchange reaction with furan is shown to be a convenient method for generating the requisite intense ion signals from molecular radical cations of dextromethorphan for MS n (sequential, product-ion scans) analysis. Little fragmentation results, concentrating ion current in the molecular species and facilitating MS n probing. Results for the odd-electron species are shown to provide some unique information compared to electrospray ionization MS n of the even-electron, protonated molecule of dextromethorphan.
