Once the researchers have worked out the make - up of electron cloud the true chemical nature of the molecule and its most reactive regions emerges. (newscientist.com)
Spectroscopy, for example, infers these changes from the way laser light interacts with electron clouds around atomic nuclei, and requires theoretical calculations to turn these data into a picture of the nuclear geometry. (sciencedaily.com)
Circle - and rod - shaped blobs represent spherical and elongated electron clouds on the manganese atoms. (sciencedaily.com)
