Spindata

Spindata provides the gyromagnetic ratio, the spin and the quadrupole moment of all isotopes carrying spin, and the electron.

Spindata is available on PyPi and can be installed as follows:

>>> pip install spindata

Alternatively, download the repository from github and run

>>> python setup.py install

To access these data call spindata's routines gamma, spin and quadrupole, respectively.

Like so:

>>> import spindata
>>> print(spindata.gamma("1H"))
>>> print(spindata.spin("17O"))
>>> print(spindata.quadrupole("17O"))

To calculate the thermal equilibrium polarization of e.g. electron spins at 6.7 Tesla and 1 Kelvin do

>>> print(spindata.polarization("E", 6.7, 1))

To calculate the spin temperature for a given polarization of a nucleus at a field of 1 T use

>>> polarizationToTemperatureAt1T(0.7, "1H")

To calculate the thermal equilibrium bulk magnetization (in A/m) of e.g. 15 mM electron spins at 6.7 Tesla and 1 Kelvin do

>>> print(spindata.magnetization("E", 6.7, 1, 15e-3))

This assumes that the Zeeman interaction dominates the Hamiltonian.
