dc.description.abstractThe $S_{1}(^{1}B_{1})\leftarrow S_{0}(^{1}A_{1})$ transition in pyrimidine has been investigated. High resolution laser induced fluorescence spectra were obtained by crossing a well collimated molecular beam with UV radiation of an intra-cavity frequency doubled ring laser. The extreme resolution enabled us to observe the molecular eigenstates of the excited electronic state. Most of the spectral features arising from the $S_{1}$ state could be interpreted in terms of a slightly perturbed axis switched asymmetric rotor spectrum. Perturbations are found both in the energy levels of the $S_{1}$ state and in the relative intensities of the transitions. This is in agreement with the much smaller background triplet level density in pyrimidime as compared to $pyrazine^{1}$. Single level lifetime measurements have been carried out for rotational states up to $J^{\prime} = 4$. The results suggest a lengthening of the lifetimes of the excited state with increasing values of $K^{\prime}$. The question put in the title will be discussed.en_US
