Calculation of the N and Cl nqcc's in
NSCl were made on the substitution structure of Beppu et al. [1].
These are compared with the experimental values in Tables 1 - 3.
Structure parameters are given in Table 3. |
|
|
|
|
|
|
|
|
|
|
|
|
In Tables 1 - 3, RMS is the root
mean square
difference between calculated and experimental nqcc's (percentage of
average experimental nqcc). RSD is the residual stand deviation
of calibration of the model for calculation of
the nqcc's. |
