Cohen, J. G. ; Wallerstein, G. Abstract Accurate radial velocities of the optical interstellar features for some of the B stars embedded in the p Oph complex are obtained by averaging results of several photographic high-dispersion spectra. In at least one case, there is a real difference between the radial velocity of the atomic features (Na 1 and Ca ii) and the molecular ones (CH and CN). We show that it is probable that the CH and CN are concentrated either in a separate cloud (i.e., region of space) from the Ca ii and Na 1 or in a cloud whose outer parts are expanding rather than in a single cloud which is contracting or rotating.
