Abstract : The spectrum of WO was studied as part of a continuing investigation of the shock-excited spectra of astrophysically important molecules. A 3-inch i.d. steel-copper shock tube was used to shock-excite tungstic anhydride powder to temperatures between 3800 and 4500K. The resulting extensive emission spectrum of WO was recorded photographically between 3400 A and 8900 A. 119 bands of WO were excited of which 99 were observed for the first time. A preliminary vibrational analysis has been made of the 'D' system and vibrational constants are given.
