The explosion mechanism associated with thermonuclear supernovae (SNIa) is still a matter of debate. Nevertheless, there is a wide agreement that high amounts of radioactive nuclei are produced during these events and that they are expected to be strong γ-ray emitters. In this paper we investigate the use of this γ-rays as a diagnostic tool. For this purpose we have performed a complete study of the γ-ray spectra associated with all the different scenarios currently proposed: detonation, deflagration, delayed detonation, and pulsating delayed detonation. Our study shows that the γ-ray emission from SNIa is, effectively, a promising tool but that has to be carefully used since it can lead to misinterpretations. We also show that 3D effects can be relevant in some circumstances and that they can provide important information about the exploding system and the thermonuclear burning front mechanism if high resolution spectra could be obtained.
