Infrared Laser Velocity Modulation Spectroscopy of SiCl+(X1Sigma+) up to v = 6.
Many fundamental and hot band absorption lines of 28Si35Cl+, 28Si37Cl+, 29Si35Cl+, and 30Si35Cl+ have been detectedbetween 630 and 700 cm-1 in a SiCl4/He discharge using diode laser velocity modulation spectroscopy. The datahave been fitted to give seven mass independent coefficients Ukl. The derived spectroscopic constants for 28Si35Cl+ include omegae = 678.24316(18) cm-1 and Be = 0.2870288(14) cm-1. The equilibrium internuclear distance is re =1.9439105(46) Å. The equilibrium dissociation energy calculated from Dunham's expanded Morse potential is De =49 431(57) cm-1.
