The study of molecular bands in the spectra of cool stars provides important information for an understanding of the stellar atmospheres. These bands include also some water vapor bands. Difficulties concerning a study of these bands arise as a result of telluric absorption. In view of these difficulties, it was decided to make use of satellite data listed in the Equatorial Infrared Catalogue 1 (EIC-1). Ground-based observations at 2.2 and 3.4 microns, and data at 2.7 microns provided by the EIC-1 were evaluated to obtain information on the 2.7 micron absorption feature in M-type Mira variables.
