the constant multipliers forXCIEandZCIEhave been expanded slightly. The ASTM D1925 method was withdrawn in 1995, but this formula still provides useful information. This index is always calculated forC/2 degrees, regardless of which illuminant and observer are chosen. The focus of this index was...
Chemists prefer to use molarity because it allows many equations, such as the ideal gas law, to apply in broader circumstances. It makes some calculations easier, however, if all quantities are in units of density. Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula HCl ...

The Hanle effect in the 4s21S0–4s4p1P1 (4226.7 ) transition in Ca I has been observed over a wide range of densities. The low density observations determine the lifetime of the 1P1 level to be 4.49 ns. Collision parameters are obtained from observations in the high density region.DOI...
The density functional theory parameter, namely, the chemical hardness (η) value, was determined for some diatomic hydride molecules using this wave function and the results are found to be in good agreement with the values obtained from the ab initio HF–SCF method. A new formula for ...
