  We present the latest results from our analysis of time resolved spectroscopy
of PG 1605+072, a high amplitude pulsating sdB star. The star is believed to
have evolved off the extreme horizontal branch, and it is uncertain whether it
pulsates in p- or g-modes. Previous studies of PG 1605+072 have found amplitude
variation and/or very closely spaced frequencies. We compare our velocity
measurements with new simultaneous spectrophotometric measurements and analyse
phase differences for the 8 frequencies found in velocity. Phase differences
between velocity, spectrophotometry and equivalent width are discussed.
