Comprehensive analysis of the FASSST rotational spectrum of S(CN)2

An automated branch-assignment algorithm for rovibrational spectra of asymmetric-top molecules

“…The quantum numbers reported in Table 1 are those determined in the present work, in perfect agreement with the assignments of Ref. [6]. All transitions of Table 1 occur within the vibrational ground state.…”

“…The algorithm assigned correctly all the investigated branches, in perfect agreement with the assignments of Refs. [6,8]. The behavior of the algorithm was analogous for all branches, thus, for brevity, here we shall discuss in detail only the results for the R branches of Tables 1 and 2.…”

“…The first is a pure rotational FASSST spectrum of S(CN) 2 (a prolate rotor) covering the spectral region between 110 250 and 374 316 MHz, with a ''hole'' between 186 000 and 191 900 MHz [6]. The average accuracy of the line frequency is approximately 50 kHz.…”

“…The experimental values for the rotational constants of S(CN) 2 [6], and the lower and upper search limits used by our Levenberg-Marquardt procedure are shown in Table 3.…”

Strong Coriolis coupling between and states of studied by millimeter-wave spectroscopy

“…Loomis-Wood type display options allow graphical assignment of the spectra. Detailed documentation and the package itself are freely available on the PROSPE website [10], and recent examples of the use of the AABS package can be found in [11][12][13].…”
