WebOct 7, 2024 · Consider a bond order of 1, we can have C-C, C-O, and C-N single bonds, with frequencies in the range of 1300-800 cm-1. Using the same atoms, but with a bond order of two, ... If we consider the C-H versus C-D stretch, we see that the C-H stretch is much more energetic than C-D. Hydrogen is a small atom and can vibrate much faster … Webrubber molecules in a crystal. When molecules, not just rubber molecules, but any molecules, form crystals, they give off heat. This is why the rubber band feels hot when its stretched. When you let go of the rubber band, the polymer molecules break out of those crystals. Whenever molecules break out of crystals, they absorb heat.
