We show that the rotational Raman response function of a molecular gas can be mimicked with a series of time‐ and phase‐shifted harmonic‐oscillator terms damped by Gaussian and exponential factors with time constants related to the parameters of molecular rotations. The proposed model is employed to derive compact analytical solutions illustrating a phase control of molecular rotations by ultrashort laser pulses and describing tailored phase masks implemented by molecular rotations driven by optimally time‐ordered pulse sequences.
