Figure 4
The variation in the angle formed by (a) the O1M—C1M—C5M—C13M and xy planes (the χ angle), and (b) the C5D—C13D—C5Di—C13Di [(i) 2-x,-y,2-z] and xy planes (the η angle) with the photodimerization process. Relation (a) can be described by the equation χ = 45.8 (4) + 0.103 (7)D with r = 0.986; (b) can be described by the relation η = 61.1 (2) − 3.4 (3)exp[−D/32.3 (7)] with r = 0.982. The numbers in parentheses represent the standard deviations in the last digits. |
