Sažetak:
We have investigated the temperatures in the atmosphere of the cool component of CH Cygni by use of highly resolved optical and near infrared spectra taken in a short epoch of the 1998-2000 active phase. TiO absorption bands belonging to α , γ , γ ', β , δ , φ and ε band systems with partly resolved rotational structure have been studied and vibrational temperatures belonging to γ 'and φ system were obtained from the relative intensities of vibrational band heads. In order to determine the effective temperature we used model atmospheres appropriate for M giants and computed synthetic spectra by line-to-line approach. Results have been discussed in view of the previously determined rotational temperature.
