The linear response theory is used to study the line shape of two coupled oscillators, decaying in two different baths, when one of the oscillators is coupled to the radiation field. The baths are considered to be thermally excited. The analysis is based on the computation of the correlation functions 〈 a i +( t ) a i (0)〉 and 〈 a i ( t ) a i + (0)〉 of each oscillator, taking the coefficients associated with the operators a i +and a i in the Heisenbemg representation as the starting point of the calculation. The line shape in different cases is also discussed.
