Description:
    Observations of 10 microwave transitions of the molecules SiO, HCN,
    HNC, SiS, HC3N, CS, SO, and 13CO are presented in a total sample
    of 47 evolved stars. The studied sources are mainly O- and C-rich
    standard AGB stars, as well as O-rich red supergiants, S-type stars,
    protoplanetary nebulae and detached envelopes. We also take into
    account observations of these transitions, as well as of 12CO J=1-0,
    from the literature.

    The observations were carried out during May and September 1991 and
    June 1992 with the IRAM 30-m radiotelescope at Pico de Veleta (Spain);
    the resolution is 1MHz for 3mm data (100GHz) and 2 MHz for 2 and 1mm
    data (150 to 300GHz).
