Strong limits on the coupling of new light particles can be obtained indirectly from astrophysical observations. Complementary and more direct searches for keV scale particles are given through molecular spectroscopy, which is---in contrast to astrophysics---in a controlled laboratory environment. In this talk, we present details on the calculation of the effects of different types of new particles on the rovibrational modes of hydrogen-like molecules, especially in the light of a current discrepancy between the best theory prediction and the most precise measurement of Tritium molecular spectra.
