WebMar 20, 2015 · The analysis of the wealth of experimental data allowed a tentative assignment of the lowest-energy levels of this enigmatic molecule based on the high-resolution spectra taken at two low temperatures. Transitions from the rotational ground state are likely identified. WebBy Boltzmann distribution formula one can calculate the relative population in different rotational energy states to the ground state. The relative population is governed by the energy difference from the ground state and the temperature of the system. A higher magnitude of the energy difference leads to lower population in the higher energy state.
