Abstract
The mass resolved (2 + 2) resonance enhanced multiphoton ionization (REMPI) spectra of methylamine (MA) via the (n(N),3s) Rydberg state were obtained in the 430-485-nm region using a time-of-flight (TOF) mass spectrometer. Th ey have the same Vibrational structure mainly due to NH2-wagging mode excit ation. The parent ion relative intensity increases at longer wavelengths. T he multiphoton ionization mechanism is discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
