摘要：
The gauge-including atomic orbital (GIAO) method for the gauge-invariant calculation of nuclear magnetic shielding constants has been implemented at the coupled-cluster singles and doubles (CCSD) level. A brief description of the theory and its computational requirements is provided. Finally, the GIAO-CCSD method is applied to calculate nuclear shielding constants of N2O with two different basis sets, the larger of which contains 153 contracted Gaussian functions. © 1995 American Institute of Physics.
