The 1H NMR of erythro and threo methyl 2,3-dichlorobutanoates were analyzed using a computer program MAOCON, a modified LAOCOON 3 program. In the spectrum of the threo form the order of the chemical shifts of protons on asymmetric carbons seems to be opposite to that reported in earlier ...
Gamage et al.: An exploration of the proton NMR problem-solving approaches Researchers have also explored the influence of different factors on students' ability to solve problems effectively (Lopez et al., 2014). In this study, the researchers used multivariate regression analysis to explore the ...
