Nitrogen gas, a seemingly inert substance that makes up the majority of the air we breathe, holds a secret within its molecular structure. The Lewis structure of the nitrogen molecule (N₂) reveals a ...

Red arrows indicate the nuclear spin axes at the positions of the N3 nitrogen atoms on the guanine (G) bases. Due to the helical structure of DNA, there is an angular deviation in the orientation of ...

McMahan and LeSar 3 first predicted that nitrogen would transform from the molecular state, in which each atom is triple-bonded with one near neighbour, to a monoatomic structure in which each atom is ...

(Nanowerk News) A recent study by researchers from Peking University demonstrates the potential of nuclear electric resonance to control the nuclear spins of nitrogen atoms in DNA using electric field ...

The development of two new methods to swap carbon atoms for nitrogen atoms in drug molecules – a common problem in pharmaceutical chemistry – could make it easier to develop new drugs. The two studies ...
