 Abstract    n o m a lo u s B e h a v io u r o f th e M e a n D ip o le P o la r iz a b ility a o f N e o p e n ta n e C (C H 3) 4 in th e T e m p e r a tu r e R a n g e b e tw e e n 2 5 0 K a n d 3 6 0 K The temperature dependence of the dynamic dipole polarizability ot(Ä) of gaseous neopentane has been re-examined in the temperature range between T = 250 K and T — 360 K at the four HeNe-laser wavelengths a = 543.51 nm, 594.11 nm, 611.97 nm, and 632.99 nm. These interferometric mea­ surements are compared with former determinations of the dynamic as well as the static dipole polarizability in the solid, liquid and gaseous state. In all cases, a shape of a(T) in the range between 290 K and 310 K has been observed which is similar to the shape of a (A) in an absorption band. This observation is connected with other physico-chemical quantities of neopentane.
