Abstract
|
|
|
|
Absorption spectra of photochromic spironaphthoxazine dye in various solvents were examined and exhibited a positive solvatochromism. The positive solvatochromism of this dye strongly suggests that the structure of open chain forms is keto type structure, 4a. The effect of structural change on the electronic spectra, on replacement of the C=C bond by C=N bond, is discussed
