it is necessary to have as many relations between the p¡ as their number.The Method of Lagranges Undetermined Multipliers.A powerful tool in the solution to extremum problems is the so-called Undetermined-Multiplier Method due to Lagrange. The problem is typically the following. An alge-
If the lowest energy electronic transition of anthracene could be removed, other aromatic hydrocarbons could be selectively excited in the presence of anthracene. The Diels-Alder reaction of maleic anhydride with anthracene can be used in practice to accomplish this. The Diels-Alder adduct of maleic anhydride and anthracene is not fluorescent, and this permits the fluorometric measurement of pyrene, diphenylstilbene, and perylene in the presence of the adduct.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
