Chemical energy carriers are still indispensable in the energy and mobility sector due to their practicability and high energy density. Thermochemical energy conversion will therefore play a major part in the transition to a sustainable energy mix in the next decades. To minimize their contribution to the emission of greenhouse gases it is necessary to both increase the efficiency of the energy conversion processes and accelerate a shift to renewable and therefore carbon-neutral alternative fuels. One promising approach for higher efficiency is combustion under higher pressure. To understand and optimize these rather new approaches, Raman spectroscopy in high resolution is able to determine both combustion species and temperature by fitting experimental Raman spectra to formerly created libraries under known conditions. For di- and triatomic molecules like O2, N2, CO, H2 or CO2 these spectral libraries can be created by directly simulating the underlying quantum mechanical processes.
