Relative intensity to percent abundance

WebIt looks like 10% has an atomic mass of 86 universal atomic mass units, and it looks like about 1% of our sample has an atomic mass of 84 universal atomic mass units. And so from this information, we can try to estimate what the average atomic mass of this mystery element is. We could calculate it as 0.82 times 88, plus, let's call this 7%, so ... WebA) C-H stretches occur at lower energies. B) C≡C stretches occur at about 1640 cm-1. C) there is no change in the dipole moment when the C≡C bond in ethyne stretches. C. In order for a vibration mode to be observable in the IR, the vibration must change the __________ of the molecule. DIPOLE MOMENT.
