Spectre radiofréquence du formaldéhyde. Substitutions isotopiques

Interphase phenomena and the condensation of liquid metal vapors. The condensation mechanism of nitrogen tetroxide vapor

“…This relationship presented a 0.5 percent standard deviation from the data and was used with the liquid density expression (equation A-2) to calculate liquid compositions. The calculated compositions are also in satisfactory agreement with the determinations of Chardon and Theobald (67).…”

Submillimeter spectroscopy of H$_2$C$^{17}$O and a revisit of the rotational spectra of H$_2$C$^{18}$O and H$_2$C$^{16}$O

“…The partial rms error of the HFS containing data [50,51] in the fit is 1.065, that from Refs. [52,53] are 0.825 and 0.567, respectively. Finally, the rms errors of our previous [29] and present studies are 0.556 and 0.903, respectively.…”

“…All further rotational data were used as in our previous analysis [29]. These involve a large body of MW and mmW data from Cornet and Winnewisser [52] along with three RF transition [53] and one mmW transition [54]. The set of spectroscopic parameters determined for H 2 C 18 O is almost the same as for H 2 C 17 O, except that H J was released in the fit of the former.…”
