Vibrational circular dichroism (VCD) is like a special camera that looks at really tiny things called molecules. Molecules are groups of atoms that stick together like a puzzle.
When we look at these molecules with our special camera, we can see that they are moving and jiggling around. Just like when you shake a toy, it wiggles and moves around.
But here's the cool part - some molecules move and wiggle in a certain way that makes them look different when light shines on them. It's kind of like how your hair looks different when you brush it one way compared to another way.
So, when we shine light through these moving molecules, we can see that the light waves bend and twist in different ways depending on how the molecule is moving. It's like how a funhouse mirror can make your body look shorter or taller depending on its shape.
Scientists use this information to study the different ways molecules can move and bend. They can even use it to figure out what kind of puzzle pieces make up the molecule!
