This is because for a molecular bond to be ‘’Infrared active’’, the vibrational mode must involve change in the dipole moment. ... Scissoring: where two atoms are moving towards or away from each … WitrynaMolecular vibrations are one of three different kinds of motion for molecules that include translational motion (when the whole molecule goes in the same direction) and rotational motion (when the molecule spins like a top) . A vibrational motion for a molecule is when the bonds between atoms within a molecule move. Think of the atoms as round balls …
Witryna31 sty 2024 · Scissoring is the sexual act between two females in which the two intertwine their legs into a “scissor” position, rubbing vulvas in order to create that sexual stimulation. It is pretty much exactly how it sounds. The “scissor” comes from the position of the legs, therefore creating the term “scissoring”.
