i) *CI"CI
ii) *CI*CI
iii) triangular H;*
iv) All isomers of C;H;F2
v) CH;CI
vi) benzene
b) Assume at = 10 the high temperature limit is reached. At what temperature does the high
%3D
temperature limit become valid for:
i) DBr (B = 4.24 cm')
ii) F"CI (B = 0.516 cm')
iii) Csl (B = 0.236 cm')
c) Obtain Jmax and for the temperatures obtained in part b) and at 500 K.
