摘要: Infrared (IR) spectroscopy of mass-selected neutral molecular clusters in supersonic beams is newly developed by combining a vacuum ultraviolet (VUV) photoionization. In this spectroscopy, the ion intensity species used as measure population corresponding cluster species. The IR excitation may cause vibrational predissociation leading to reduction, which appears dip spectrum photoionization signal. This method can be called VUV-ionization detected (VUV-ID-IRPDS). applied spectra ammonia dimer and trimer.
