Q: In IR spectroscopy, what type of molecular vibrations are primarily detected?

Solution: IR spectroscopy detects molecular vibrations, specifically stretching and bending of bonds, which correspond to different functional groups.

Steps: 5

Step 1: Understand that IR spectroscopy is a technique used to study molecules.
Step 2: Know that molecules are made up of atoms connected by bonds.
Step 3: Recognize that these bonds can move in different ways, which are called vibrations.
Step 4: Identify the two main types of vibrations: stretching (where bonds get longer or shorter) and bending (where bonds change angle).
Step 5: Realize that different functional groups in a molecule will have specific vibrations that can be detected by IR spectroscopy.
