Global analysis of data on the spin-orbit coupled A1Σu+A^{1}\Sigma_{u}^{+} and b3Πub^{3}\Pi_{u} states of Cs2

We present experimentally derived potential curves and spin-orbit interaction functions for the strongly perturbed $A^{1}\Sigma_{u}^{+}$ and $b^{3}\Pi_{u}$ states of the cesium dimer. The results are based on data from several sources. Laser-induced fluorescence Fourier transform spectroscopy (LIF FTS) was used some time ago in the Laboratoire Aim\'{e} Cotton primarily to study the $X ^{1}\Sigma_{g}^{+}$ state. More recent work at Tsinghua University provides information from moderate resolution spectroscopy on the lowest levels of the $b^{3}\Pi_{0u}^{\pm}$ states as well as additional high resolution data. From Innsbruck University, we have precision data obtained with cold Cs$_{2}$ molecules. Recent data from Temple University was obtained using the optical-optical double resonance polarization spectroscopy technique, and finally, a group at the University of Latvia has added additional LIF FTS data. In the Hamiltonian matrix, we have used analytic potentials (the Expanded Morse Oscillator form) with both finite-difference (FD) coupled-channels and discrete variable representation (DVR) calculations of the term values. Fitted diagonal and off-diagonal spin-orbit functions are obtained and compared with {\it ab initio} results from Temple and Moscow State universities

The Study of Volatile Fractions of Carrot Raw Material of “Bright” and “Nantes Kharkiv” Varieties

Common carrot is widely cultivated in many countries as a food plant. Raw material of this plant has antispasmodic, antibacterial, cytotoxic, antiparasitic, cardioprotective, and hepatoprotective activity.Common carrot in non-pharmacopoeial Ukraine, therefore, it requires in-depth pharmacognostic study. In addition, research of its most common varieties in Ukraine, namely “Bright” and “Nantes Kharkiv” remains relevant.The aim of research was determination of the volatile fractions components of aerial part and roots of Common carrot of “Bright” and “Nantes Kharkiv” varieties.Methods. Gas chromatography method was used for determination of Common carrot volatile fractions.Results. In result of the study, 32 compounds were identified in the volatile fraction of Common carrot aerial part of “Bright” variety, 34 compounds were determined in roots of the same sample. 20 components were found in the volatile fraction of Common carrot aerial part of “Nantes Kharkiv” variety, and in its roots 39 compounds were identified.All the volatile fractions studied characterized by the presence of Caryophyllene and Caryophyllene oxide in high amount. Sesquiterpene alcohol Carotol was determined in all the samples studied.Conclusion. According to the results of the given research, marker compound Carotol was found in all Common carrot objects studied. The obtained data can be used for standardization of aerial part and roots of Common carrot of “Bright” and “Nantes Kharkiv” varietie
