摘要：

An analysis of O-17 carbonyl chemical shifts of 50 substituted benzaldehydes leads to an empirical equation, delta(cal)(O-17) = 564.0 + SigmaDeltao + SigmaDeltam +SigmaDeltap + C, for calculating O-17 chemical shifts. This equation is based on a linear regression analysis using 11 substituent parameters and leads to good conformity with the expected data. Copyright (C) 2004 John Wiley Sons, Ltd.
