β¦ Synopsis
A new investigation of the CF 2 35 Cl 2 ground state rotational spectrum in the 50 -100 GHz frequency range gave an opportunity to improve the accuracy of rotational and quartic distortion parameters by an order of magnitude and to determine values of six sextic centrifugal distortion parameters. A special technique was used to process line profiles of unresolved or partially resolved hyperfine structures of rotational transitions. It allowed us to improve significantly values for the diagonal parameters of quadrupole coupling aa , ( bbcc ) and to determine the off-diagonal parameter ab .

The ground state rotational spectra of CH 2 |CH 35 Cl and CH 2 |CH 37 Cl have been measured in the millimeter-wave and submillimeter-wave ranges. These new data have been used to improve notably the accuracy of the rotational and centrifugal distortion constants. Finally an ab initio structure has b
The ground state rotational spectrum of \(\mathrm{CHF}_{2} \mathrm{Cl}\) has been observed and analyzed in the frequency region \(70-1280 \mathrm{GHz}\). Transitions with values of \(J\) up to 80 have been observed and the centrifugal distortion analysis of the spectrum has been performed using both
Two mechanical models have been presented in this paper for structural failure prediction of piping systems conveying liquids subjected to pressure transients. One model takes into account the axial fluid-structure interaction (FSI) phenomenon between fluid and pipe motion, whereas the other refers
