Web[en] The molecular structure of the linear C2S and C3S molecules were studied by a quantum chemical method. The calculated rotational constant is 6438 MHz for C2S and 2888 MHz for C3S. After vibrational correction, these values agree closely with experiment. The calculated dipole moments of C2S and C3S are 2.8 D and 3.6 D, respectively. The cement chemist notation is not restricted to cement applications but is in fact a more general notation of oxide chemistry applicable to other domains than cement chemistry sensu stricto. For instance, in ceramics applications, the kaolinite formula can also be written in terms of oxides, thus the corresponding formula for kaolinite, Al2Si2O5(OH)4, the powder toy free https://quiboloy.com
