Abstract The authors have observed substantially reddened stars in the ρ Oph and the T Cha clouds, as well as individual hot stars associated with nebulosity in the λ5780, 5797 diffuse interstellar line region. They find λ5780 to be generally weak, except in Z CMa and stars SR 3 and SR 5 in the ρ Oph cloud. The line at λ5797 is weak, relative to λ5780 in all of the program stars. The authors confirm the suggestion by others that λ5780 and λ5797 are due to different sources. Finally, they discuss the implications of the weakness of these bands in regions of high gas and dust density, as well as an enhanced radiaton field due to the presence of recently formed stars.
