摘要: Abstract The triple ion [ ( CH 3 ) 4 N + · PF 6 - ], generated by electrospray ionization of tetramethylammonium hexafluorophosphate, is characterized collision-induced dissociation and infrared spectroscopy the mass-selected gaseous in range from 1000 to 2000 cm−1. Quantum chemical calculations are used elucidate structures energetics its subunits for assignment frequencies. bands observed gas-phase match quite closely with those bulk substance, suggesting that this particular kind associate structural differences between condensed state almost negligible.
