Received April 29, 1981.
Infrared Spectroscopy was used to determine the numbers of base pairs for yeast 5.8S RNA and 5.8S RNA. The spectra were re-corded at 20°C and 50°C, where tertiary interactions are assumed to be of less importance. It may be concluded that the structure of both RNAs is highly ordered and that there are large contributions of tertiary interactions. The results are compared with derived from structural models that were proposed in the literature as well as with data previously published for prokaryotic 5S RNAs.
