The molecule CS has been detected in interstellar clouds using microwave spectroscopy. Predict which rotational level in "CS will have the greatest population at a temperature of 70 K. The masses of the two atoms are m 12.00 u and m = 31.972 u and the equilibrium bond length of the molecule is 1.534 A. Note: The Boltzmann constant, k, has a value in wavenumbers of 0.69503 cm (B) A (A) 3 (D) 6 5 (C)
