Larmor (ENDOR) frequency of nuclear spins.
freq = larmorfrq(Nucs,Fields)
larmorfrq
computes the Larmor frequencies (in MHz)
for the nuclear spins given in Nucs
at magnetic fields
(in mT) given in Fields
.
Nucs
is either a cell array of nuclear isotope symbols
or a character array with a comma-separated list of nuclear isotope symbols,
e.g., '14N'
or {'14N','1H'}
or '63Cu,65Cu'
.
Fields
is a vector of magnetic field values in mT,
e.g. 350
or [350 365 380]
or
1200:10:1300
.
freq
contains the Larmor (ENDOR, NMR) frequencies in MHz.
Each column contains the frequencies of one nucleus.
The ENDOR frequencies of the two naturally occurring nitrogen isotopes at a typical X-band magnetic field value are
larmorfrq('14N,15N',350)
ans = 1.0772 1.5110
The same result can be obtained by using a cell array instead of the comma separated list of isotopes
larmorfrq({'14N','15N'},350)
ans = 1.0772 1.5110
The ENDOR frequency of protons for a series of magnetic field values can be obtained with
larmorfrq('1H',350:10:400)
ans = 14.9021 15.3279 15.7537 16.1794 16.6052 17.0310
