Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen.

Mass Spectral Fragmentation Patterns of Heterocycles. VII. Reinvestigation of Fundamental Processes in Phenothiazines
Electron impact induced fragmentation patterns of simple phenothiazines have been reinvestigated using metastable ion studies, exact mass measuremants and deuterated derivatives.Secondary fragmentation processes involving ions m/e 198, 171, 167, 166, 154, 140 and 139 have been clarified.Mechanisms for the release of sulfur (SH. and CSH.) nitrogen (HCN and H2CN.) containing fragments from phenothiazine molecular ion are proposed based on the deuterium content of the daughter ions obtained from 1,9-dideuteriophenothiazine.A revised mechanism for the expulsion of ketene from 10-acetylphenothiazine is suggested based on the fragmentation pattern of the 1,9-dideuterioderivative.The composition of m/e 140 was determined by high resolution measurement to be C10H6N and not C11H7 as previously reported.
