Velocity modulation and magnetic modulation methods as a means of selective modulation of ionic species have been applied for the first time to emission spectroscopy using a grating spectrometer. magnetic modulation can achieve conc~nt~tion modulation effects of up to 100% for ionic species such as
4 /He discharge using diode laser velocity modulation spectroscopy. The data have been fitted to give seven mass independent coefficients U kl . The derived spectroscopic constants for 28 Si 35 Cl Ο© include e Ο 678.24316(18) cm Οͺ1 and B e Ο 0.2870288(14) cm Οͺ1 . The equilibrium internuclear distance
The lowest six vibrational hot bands of CF+ have been measured in a heIium/CsF, discharge by velocity moduiation laser spectroscopy. A total of 56 transitions has been fitted to Dunham expansion for v = O-7, yielding the parameters: we = 1792.6654(18) cm-\*, Be = 1.7204176(75) cm-', r, = -13.22968(5
