Abstract
Gas phase BC was made in a composite wall $Cu/B_{4}C$ hollow cathode discharge operated with a flow of Ar gas. The emission from the discharge was observed with the Fourier transform spectrometer associated with the National Solar Observatory at Kitt Peak. The observed lines near $17900 cm^{-1}$ are assigned to the 0-0 band of the $B^{4}\Sigma^{-}X^{4}\Sigma^{-}$ transition of BC. The BD and CuD nolecules were produced by passing $D_{2}$ gas through the $Cu/B_{4}C$ hollow cathode. The $A^{1}\Pi-X^{1}\Sigma^{+}$ transition of BD and the $A^{1}\Sigma^{+}-X^{1}\Sigma^{+}$ transition of CuD were analysed. The rotational structure of the two main isotopes of $Cu, ^{63}Cu$ and $^{65}Cu$, was resolved. ZnD was produced in a Zn/Ni/C hollow cathode operated with $D_{2}$ and argon gases. All the branches of the $A^{2}\Pi-X^{2}\Sigma^{+}$ transition were observed in our spectrum. The rotational structure of the three main isotopes of $Zn (^{64}Zn, ^{66}Zn$ and $^{68}Zn)$ was resolved in most of the branches.
