New Fourier transform emission measurements were obtained for HF and DF at a temperature of 2300 degrees C. Both pure rotation and vibration-rotation lines were measured with a precision of about 0.0005 c(m)(-1). These new lines were combined with previously measured data to give improved rotational constants for the vibrational levels v = 0-5. The HF molecule is the most convenient monitor of F-19 abundances in cool stars.
