A survey of the CO J= 4-3 transition has been made towards a sample of seven galactic molecular clouds. These data have been combined with spectra for the lower CO transitions to examine how they vary in line shape with different transition. Such variations are examined using LVG modelling techniques to obtain estimates of the physical state of the emitting gas. The authors discuss the implications and importance that observations of these submillimetre wavelength transitions have in refining knowledge of the gas in molecular clouds.
