Abstract

The electronic spectrum of silicon methylidynes was obtained using a pulsed discharge jet source and continuous wave excitations, to analyse the hyperfine stucture and stark effects. The proton hyperfine structure was produced with a single upper state Fermi contact parameter and electric dipole moment was determined. The dependency of the parameters on the ground state were depicted on the basis of occupied molecular orbitals. It was shown that the fermi contact parameter and dipole moments including single and double substitution levels of theory were in agreement with the experimental values.
