Isomer-selective detection of microsolvated oxonium and carbenium ions of protonated phenol: Infrared spectra of C6H7O+-L-n clusters (L=Ar/N-2, n <= 6)
Infrared photodissociation (IRPD) spectra of clusters composed of protonated phenol (C6H7O+) and several ligands L are recorded in the O-H and C-H stretch ranges using a tandem mass spectrometer coupled to a cluster ion source. The C6H7O+-L-n complexes (L=Ar/N-2, n=1-6) are generated by chemical ionization of a supersonic expansion. The IRPD spectra of mass selected C6H7O+-L-n clusters obtained in various C6H7O+-L-m fragment channels (m
