Molecular ions play crucial roles in the astrochemistry associated with star formation and planetary atmospheres. In this project we have studied three fundamental cations CNHn+ (n = 9,4,6) using action spectroscopic techniques in a 22−pole ion trap at a nominal temperature of 4 K [1]. The fundamental diatomic CN+ [2] as well as the protonated methylene imine, H2C=NH2+, and protonated methyl amine, H3C−NH3+, were all studied by their pure rotational spectra in the millimeter-wave region employing the method of rotational state-selective He-attachment [3]. CN+ and H2C=NH2+ were also studied at high spectral resolution in the infrared using Laser Induced Inhibition of Complex Growth (LIICG) [1,4].
