Abstract

The emission spectrum of HfO has been investigated in the 400 nm to 5 mu m spectral region with a Fourier transform spectrometer. The bands were excited in a hafnium hollow cathode lamp in the presence of neon and a trace of oxygen. In the 6900-8000 cm(-1) region, four new sequences of bands were observed with the 0-0 Q heads at 7060 cm(-1), 7355.4 cm(-1), 7376.8 cm(-1), and 7929.5 cm(-1). These bands have been identified as the (3) Pi(0+)-3 Delta(1), (3) Pi(0-)-(3) Delta(1), (3) Pi(1)-(3) Delta(2) and (3) Pi(2)-(3) Delta(3) subbands of the b(3) Pi-a(3) Delta transition. The rotational analysis of the 0-0 and 1-1 bands of each subband has been performed and the equilibrium rotational constants for each spin component of the b(3) Pi and a(3) Delta states have been obtained.
