An isotopically enhanced sample has nDI moles of deuterated hydrogen iodide and nHI moles of common HI at 398 K. Comparison of the infrared intensities of the v = 1 S 2 transition inds a ratio of 0.100 for DI molecules (ve = 1640cm-1 ) in the v = 1 state to HI molecules (ve = 2310cm-1 ) in the v = 1 state. What is the ratio nDI>nHI in the entire sample?
