Popis:	The authors describe a new method for obtaining vibrational overtone spectra of polyatomic molecules in supersonic expansions that uses low-energy electrons to ionize the vibrationally excited molecules. Measuring the excitation spectrum of water in the region of the third overtone of the OH stretching vibration (4..sigma../sub OH/) demonstrates the technique. The ionization process is probably not direct but may occur by electron impact excitation to vibrationally and electronically excited states from which the neutral molecule is subsequently ionizes
