The temperature broadening and shift of phononless lines of the impurity centers due to interaction of intraimpurity and crystal oscillations are investigated. It is shown that the width of phononless lines as a function of the mode-interaction parameter has a maximum, which is reached at parameters corresponding to the appearance of unstable oscillations. Numerical calculations show that the rate of temperature broadening is limited at the level of 0.5 cm−1/deg.
