The temperature dependence of the nuclear response function is studied with the random phase approximation. It is found that the strength distributions are rather stable for temperatures up to about 3 MeV. Thermal excitations do affect, however, the low-energy regions of the nuclear spectrum.

Photoabsorption cross sections were measured for Na,+ , n=9,21, and 41 at two temperatures, a low one at T= 130 K, and a high one with T> 300 K. A large, unexpected temperature effect is observed. The single, broad peaks observed at high temperature become narrower at 130 K for n = 2 1 and 4 1. For
## Abstract The high temperature ^13^C NMR spectra of the methyl esters of deuteroporphyrinโIX and protoporphyrinโIX, and octaethylporphyrin show sharp discrete signals for the inner macrocycle carbon resonances. The temperature dependence of these shifts is discussed.
