Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

These clusters of strongly bonded atoms are called molecules. See how they're represented by two circles of different size and colour that are joined together. This particle diagram represents ...

Spectroscopic techniques, such as absorption and emission spectroscopy, use angstroms to identify and quantify chemical species based on their characteristic spectra. Angstroms are used to describe ...

H2O. An almost negligible proportion of a few per million consists of "heavy water," in which the hydrogen atoms (H) are ...

Hydrogen bonds result when hydrogen and oxygen atoms between water molecules ... In this way, we can create separate spectra for non-interacting and interacting molecules," Roke says.

The first pulse — the pump — creates excited states in molecules ... spectra were taken to distinguish the photoelectrons emitted by Br 2 from those of the two dissociated Br atoms, but ...

At 13 atoms, the compound, called 2-methoxyethanol, is one of the largest molecules ever identified ... Fried began by measuring the rotational spectrum of 2-methoxyethanol samples in the lab ...
