Experimental results of homogeneous nucleation of supersaturated vapors

Abstract

An r0 structure is determined for dimethylamine from earlier microwave data. With the constraint δr0(CH–CD)=δr0(NH–ND), CH bond lengths of 1.0958, 1.0981, 1.1060 A≡ are obtained, in excellent agreement with earlier predictions from ‘‘isolated’’ CH stretching frequencies. The new value of r0NH of 1.011 A≡ is significantly shorter than the earlier rs value of 1.022. The angular asymmetry of the methyl group is greater than previously supposed.
