Photoelectric spectral scans at 30-1 resolution of 9 dwarfs, 10 giants and 6 supergiants with spectral types GO to M5 are presented. All stars were observed every 4 j from X3300 to 47000. Absorption features observed at this resolution coincide with.' strong atomic lines of Fe I,II, Ca I,II, MgI, and Na I; vibrational bands of the electronic transitions of TiO, MgH, CaH, SiH, AlH, CN, CH, C 2 , OH, and NH. The dependence of the 4 3 7 40 Fe I blend and the X3440 depression on temperature is discussed.
