title: Theoretical study of 31P, 31P coupling constants in cyclotriphosphazenes.
abstract: Several scalar coupling constants (mainly 31P, 31P) were calculated for 10 cyclotriphosphazenes and compared with experimental results when available. Although the experimental values cannot be reproduced, the calculated values are proportional to the experimental values. Some difficult cases, such as 19F, 19F couplings, are discussed.
