Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 103-85-5, Name is 1-Phenylthiourea. In a document, author is Thakkar, Ajit J., introducing its new discovery. Recommanded Product: 103-85-5.
Dipole oscillator strength distributions, sum rules, mean excitation energies, and isotropic van der Waals coefficients for benzene, pyridazine, pyrimidine, pyrazine, s-triazine, toluene, hexafluorobenzene, and nitrobenzene
Experimental, theoretical, and additive-model photoabsorption cross sections combined with constraints provided by the Kuhn-Reiche-Thomas sum rule and the high-energy behavior of the dipole oscillator strength density are used to construct dipole oscillator strength distributions for benzene, pyridazine (1,2-diazine), pyrimidine (1,3-diazine), pyrazine (1,4-diazine), s-triazine (1,3,5-triazine), toluene (methylbenzene), hexafluorobenzene, and nitrobenzene. The distributions are used to predict dipole sum rules S(k) for -6 <= k <= 2, mean excitation energies I(k) for -2 <= k <= 2, and isotropic van der Waals C-6 coefficients. A popular combination rule for estimating C-6 coefficients for unlike interactions from the C-6 coefficients of the like interactions is found to be accurate to better than 1% for 606 of 628 cases (96.4%) in the test set. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 103-85-5 help many people in the next few years.
