We report on the results of medium-resolution spectroscopy of GRS 1915+105 in the near-infrared H and K band using the 8 m VLT at ESO. We clearly identify absorption bandheads from (12)CO and (13)CO. Together with other features this results in a classification of the mass-donating star in this binary as a K-MIII star, clearly indicating that GRS 1915+105 belongs to the class of low-mass X-ray binaries (LMXB).
