Abstract (from CDS):

The high resolution spectrum of NML Cyg observed with the ISO-SWS in its slow-speed grating mode (2.4-45µm) shows a wealth of features never seen before in previous observations. These include ro-vibrational lines of H2O at 2.7 and 6.2µm, of OH between 3 and 3.5µm and a deep absorption band of CO2 at 4.26µm. We also report on the detection of pure rotational emission lines of H2O between 35 and 45µm and of the 34.6µm absorption line of OH which is thought to pump the well known 1612 MHz OH maser line. There are two, as yet, unidentified features at 33 and 40µm which may be related to silicate dust.
