The aniline molecule is nonplanar, with its NH 2 group lying at an angle θ of approximately 42 • to the plane of the benzene ring. Substituents on the phenyl ring alter this out-of-plane angle as well as other molecular properties such as the ring bond lengths and angles, the barrier to inversion E

Oligomeric polysiloxanes having the spirobenzopyran moiety and various substituents were prepared. The polymers were photochromic; the color changed from colorless to red on U V irradiation and the color faded on visible irradiation or on standing in the dark. The thermal decoloration was depressed

## Abstract ^13^C chemical shifts and ^31^P,^13^C coupling constants are reported for nine 1‐hydroxyalkylphosphonic and two additional phosphonic acids. The α‐substituent‐induced chemical shifts (α‐SCS) of the phosphonate group were calculated and their non‐additivity was observed. Good linear corr
