	abstract = {This paper presents data showing that in dilute aqueous solutions of butanone, 3-pentanone, cyclohexanone, di-tert-butyl ketone, and acetaldehyde the addition reaction of muonium atoms occurs with a rate constant close to 1 x 10(8) M-1 s(-1). The same value was obtained previously for acetone. Thus the reaction rate is virtually independent of the group attached to the C=O, be it a methyl, methylene, tert-butyl, or even a hydrogen atom. This is in sharp contrast to the reactivity of ordinary H-1 atoms, whose rate constants are much slower and dependent on adjacent groups. In fact muonium and H-1 react by different mechanisms, to form different products, so their rate ratio represents a complex kinetic isotope effect.},
