We analyze and discuss the temperature dependent anomalies introduced into the rotational-vibrational (ro-vibrational) Raman signals due to angular-truncated transmission through interference filters (IF). For that we use equations for ro-vibrational Raman scattering proposed by literature to calculate the molecular backscatter cross-sections of N2. The results allow us to quantify the extend of these temperature dependent anomalies with respect to the interference filter characteristics such as the central wavelength and bandwidth. As a preliminary result it turned out that transmission through narrow-band interference filters introduces only small anomalies.
