Abstract
The paper presents the preliminary results of a study of infrared spectra of Am stars in the 8400–8800 region. This is part of a large program of classification of the cool components of composite spectra. We analize the infrared spectra of 33 Am stars and show that 22 can be explained as composites of an Am star plus a normal dwarf, whereas the remaining 11 are formed by an Am plus a metal deficient star. We discuss some of the difficulties found and speculate on the consequences of our findings.
