We first describe some characteristics of our compact photoelectron analyzers capable of high- resolution (1 - 2 cm-1) cation spectroscopy of molecules in two-color (approximately ega 1, approximately ega2) laser experiments of resonantly enhanced multiphoton ionization. Threshold ionization photoelectrons lower than a few cm-1 are collected as a function of approximately ega2 by applying a pulsed electric field at 500 ns at each laser shot, while energetic photoelectrons are removed by angular- and time-resolved discrimination. Second, we demonstrate a rotational spectrum due to NO+ obtained by this technique to examine our energy resolution. Third, we mention a few examples of low-frequency vibrational spectra of cation radicals: (1) rotational isomers, (2) Ar-NO van der Waals complex, and (3) aniline- Arn complexes (n = 1,2).
