Microwave-optical double resonance experiments have been carried out on the JO,, rotational levels of the 4' A'A, excited state of thioformaldehyde (HaCS). The number of microwave transitions to high rovibronic levels of the ground state observed in a given frequency range increases in a roughly lin

β¦ Synopsis
Bands of the (B^{3} \Sigma_{u}^{-}-X^{3} \Sigma_{\mathrm{g}}^{-})system of oxygen have been photographed in absorption at high resolution following the flash photolysis of ozonized oxygen. The bands have (v^{\prime}=0) and (v^{\prime \prime}=11) to 18. Improved molecular constants for the ground state levels are obtained from rotational analyses of the bands.
