| Abstract: | The mass resolved (2 + 2) resonance enhanced multiphoton ionization (REMPI) spectra of methylamine (MA) via the (nN,3s) Rydberg state were obtained in the 430-485-nm region using a time-of-flight (TOF) mass spectrometer. They have the same vibrational structure mainly due to NH2-wagging mode excitation. The parent ion relative intensity increases at longer wavelengths. The multiphoton ionization mechanism is discussed. |
