Abstract

Fourier transform spectra of HCN and $H_{2}CO$ were obtained using the FTS spectrometer at the National Solar Observatory, at Kitt Peak, Arizona. Samples were contained in a 6 m multipass White Cell and the resolution was 0.01 to $0.02 cm^{-1}$. 910 lines of three isotopic species of HCN were obtained in the $3300 cm^{-1}$ region with an accuracy of approximately $0.0001 cm^{-1}$. Spectra were analysed to obtain band origins, rotational constants and $ell$-doubling constants. For $H_{2}CO$, asymmetric rotor parameters and band origins were obtained for $3\nu_{2}, 2\nu_{2} + \nu_{6}$ and $\nu_{3} + \nu_{5}$ bands. Lines could be fit to a precision of $0.01 cm^{-1}$ with partial treatment of perturbations. A 432 m optical path length was used for $H_{2}CO$ measurements.
