Abstract

Refrachor with a symbol F a new physical constant proposed for the first time in 1951 by Joshi and Tuli defined by the equation F = –P log( n D 20 ${n}_{\mathrm{D}}^{20}$ –1) where P is the parachor and n D 20 ${n}_{\mathrm{D}}^{20}$ is the refractive index, is now used in our present work to calculate the percentage composition of 1H- and 2H-tautomers of tetrazole, 1,2,3-triazole, and imine-enamine tautomerism of acetaldimine in their equilibrium mixtures.

Refrachor (F)--七十年前的工具和当代观察:估算四氮唑和 1,2,3 三氮唑的 1H 和 2H 同分异构体的平衡成分,以及乙酰二胺-乙烯基胺同分异构体的亚胺成分
F = -P log( n D 20 ${n}_{\mathrm{D}}^{20}$ -1) 式中,P 为抛物线,n D 20 ${n}_{\mathrm{D}}^{20}$ 为折射率、在我们现在的工作中,我们用它来计算四氮唑、1,2,3-三氮唑的 1H 和 2H 同分异构体以及乙酰二胺的亚胺-烯胺同分异构体在它们的平衡混合物中的百分比组成。
