## Abstract Carbon‐13 spectra of twelve chlorofluoropyridines (C~5~CI~n~F~5βˆ’n~N), of known structure, have been assigned and an assessment has been made of the degree of additivity of substituent chemical shifts (SCS). Reasonable additivity is observed for pyridine derivatives but little regulatiry
