Dimethylaniline

[Since you're not a logged-in user, I fear you will never see this unless I write it here. Please use complete sentences; do not begin an article with a dictionary definition, or with the words "consists of a ring...", with no subject. Please follow the highlighting convention: The title word or title phrase should be highlighted in the first line. I moved your material from "transvers" to "transverse wave" and redirected, and made your ditionary-definition-style phrase into a complete sentence, following the highlighting convention. You tried to link to "oscilates" (spelled incorectly); I changed this to a link to "oscillation" (using the verb as the article title doesn't make sense, and the "oscillation article already existed). The word on which one clicks is still "oscillates", not "oscillation", but the link is to "oscillation".]
