✦ Synopsis

Upon request of experimentalists now engaged in high-resolution spectroscopic investigations of the molecule KRb, we have determined the potential energy of electronic states 2Sϩ1 ⌳ (ϩ) correlating up to the limit K(5p) ϩ Rb(5s) and of electronic states ⍀ (ϩ/Ϫ) correlating up to the limit K(4s) ϩ Rb(4d 2 D 3/ 2 ) in a large range of internuclear distance R. For the five states so far observed, the agreement between calculated and experimental molecular constants is good with ⌬R e Ͻ 0.08 Å, ⌬ e Ͻ 6 cm Ϫ1 , and ⌬T e Ͻ 140 cm Ϫ1 . Extensive numerical data for energies versus R have been listed in a data base available at http://www.idealibrary.com.

The theoretical conformations of poly (Gly-Ala-Glu) have been studied. This peptide was chosen as a model for the glycine led triads of the polar regions in collagen. The most favorable conformations are found to be based on the extended and folded forms of the 27 helix ( 2 ~~ and 27b). It is sugges
