PURELY ROTATIONAL COHERENCE AND SUB-DOPPLER SPECTROSCOPY. Guided by the theoretical decay simulations of Fig. 46, the first unambiguous observation of thermally averaged rotational coherence effects was made for excitation and detection of the S, - S00° band of jet-cooled t-stilbene.47 Observed fluorescence decays are shown in Fig. 47 theory and experiment match very well. The recurrences associated with rotational coherence effects in fluorescence have been observed for a number of other species as well. Among these species are t-stilbene-, 2, t-stilbene-argon complexes,48 and t-stilbene-he-lium complexes.71 The recurrences allow the determination of the excited-state rotational constants to a high degree of accuracy. [For example, for t-stilbene we find j(B + C) to be 0.00854 + 0.00004 cm-1.] The indications are that with currently available temporal resolution, rotational coherence effects should be observable in a multitude of species and should allow the accurate determination of such species excited-state rotational constants. 

Potential energy surface, van der Waals energy spectrum, and vibronic transitions in an r-triazine-argon complex have been studied by ab initio methods <2006JCP044310>. 

It has been shown that the relaxation of vibrational levels of the tetrazine-argon complex is sequential (IVR prior to VP). It would be important to know whether such a behavior is characteristic for a large class of... 

In this paragraph we will concentrate on ab initio calculations of the dipole moment of methane-argon complex relevant to the atmospheres of Titan and Earth. Also, the analytical form of the dipole moment components is presented for the case of rigid mediane molecule. 

Molecular clusters are also formed during the adiabatic expansion of free jets. Examples are the production of benzene clusters (CgHgjn and their analysis by two-photon ionization in a reflectron [9.42], or the determination of structure and ionization potential of benzene-argon complexes by two-color resonance enhanced two-photon ionization techniques [9.43].
