WebA close observation of crystal data (Table 1) reveals that in the case of l-methionine, l-arginine, l-cystine and l-aspargine the expected product picrate is not formed but only the picric acid crystallizes out from the equimolar solution of amino acid and picric acid. WebAug 7, 2013 · There have been several reactions that have been shown to be surface structure dependent through the use of single crystal studies. One important example of a surface structure specific reaction was found in the platinum catalyzed exchange of hydrogen and deuterium [55, 56].The surface structure sensitivities in the reaction …
