I. Compute the ratio of the Zero point energy for the diatomic deuterium and tritium substituted compound XD and XT Ii. From this and the C-H stretching frequency of 3000 cm-1, compute the C-D and C-T stretching frequency.
iii. What is the Zero point difference bin kJ
iv. Predict the value of kH/kT at 300k?
v. What is the ratio of kD/kT?

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
