| Abstract: | Vibrational temperatures in the atmospheres of nine M type giants of luminosity class III and subtypes M2-M8 located in the
Galactic plane have been determined from the γ band system of the TiO molecule. The relationship between T
exc and T
eff has been established in agreement with the chosen T
eff calibration scale. The deviation of T
exc with recspect to T
eff for our stars has been used as an indicator of the depth of the atmospheric layers in which the molecular bands are formed.
