Abstract: Abstract Gas-phase standard enthalpies of formation of selected ureas and s-triazines were calculated at the CCSD(F12∗)(T)/cc-pVTZ-F12//ωB97X-D/cc-pVTZ level of theory by employing isodesmic reactions. The following values were obtained (T = 298.15 K, units: kJ mol−1, estimated confidence interval 95%):… read more here.

Abstract: In this paper, the multiple-mode interference (MMI) and phase standard deviation of very low frequency (VLF) wave propagation in an anisotropic earth–ionosphere waveguide are treated analytically. The phase stability of a VLF wave is dependent… read more here.
