Crystal structure of 5,7-dihydroxy-3-methylcoumarin.
coumarin derivatives are of great interest in view of their sensitizing abilities in photodynamic effects and their wide occurrence in the plant kingdom. Umbelliferone, 7hydroxycoumarin, which has been known as a strongly fluorescing compound, also exhibits chemiluminescence.1 On the other hand, 7-hydroxy-4-methyl coumarin2 (Fig. 1-(I))has been applied in laser gain studies. The title compound ...
متن کاملCrystal structure of 7,8-dihydroxy-4-methylcoumarin.
The structure of 7,8-dihydroxy-4-methylcoumarin was determined by an X-ray diffraction method. The compound crystallized in the triclinic space group P1, Z = 2, with a = 7.631(2), b = 9.456(5), c = 7.075(3)A, alpha = 103.13(3), beta = 91.84(3), gamma= 68.21(3) degrees, and V= 460.9(3)A3. The X-ray crystal structure was also compared with those of 5,7-dihydroxy-4-methylcoumarin and 7-hydroxy-4-m...

The word “Layers” refers to the deferent layers within a communications system—such as an organization’s or person’s website—that together make communication possible. The idea of “Layers” is attributed to Yochai Benkler, Professor of Law at New York University, who first used it to describe a communications system that is divided in three distinct layers: 1. The “physical” layer across which c...

The transition to turbulence in pipe and plane Couette flow differs from the better understood situation of Taylor-Couette or Rayleigh-Bénard flow in that the laminar profile is stable against infinitesimal perturbations for all Reynolds numbers. Moreover, even when turbulent flow is established, it can spontaneously return to laminar flow. These observations are compatible with the formation o...
