Abstract:
    We present simultaneous observations of several rotational lines of
    ^28^SiO in the v=1, 2, 3, and 4 vibrationally excited states toward
    O-rich evolved stars. All the data were taken in a relatively short
    period of 65 days, which allows a comparative study of the ^28^SiO
    maser lines intensities and profiles. The observed differences
    concerning intensity and line shape among the different maser lines
    suggest that infrared overlaps deeply affect the pumping of some SiO
    masers. We qualitatively discuss this effect with consideration to the
    IR overlaps at 8 {mu}m between the various SiO isotopomers and between
    ^28^SiO and water vapor
