Nuclear spin quantum number, g value, quadrupole moment and natural abundance.
I = nucdata(Isotopes) [I,gn] = nucdata(Isotopes) [I,gn,Q] = nucdata(Isotopes) [I,gn,Q,w] = nucdata(Isotopes)
This function returns the nuclear spin quantum number I
, the
nuclear g value gn
, the electric quadrupole moment Q
(in barn, see barn) and the
natural abundance of the nucleus or nuclei specified in Isotopes
.
Isotopes
is a character array giving the mass number and the
chemical symbol of the element, e.g. '14N'
or '63Cu'
.
If Isotopes
is a comma-separated list of isotope labels,
the function returns lists of all nuclear spins, g values, quadrupole
moments and abundances in vector form.
EasySpin's nuclear isotope database contains all stable non-zero spin nuclei and some radioactive
nuclei with decay times longer than about a year. If a nucleus is not in the
database, nucdata
errors.
