r1n_dnp.m

A simple model for nuclear longitudinal relaxation rate due to the presence of an unpaired electron in cryogenic DNP settings.

Syntax

   R1n=r1n_dnp(B0,T,g,T1e,T1n_bulk,r,bet)

Arguments

   B0       - main magnet field, Tesla

   T        - absolute temperature, Kelvin

   g        - electron g-factor, Bohr magneton units

   T1e      - electron longitudinal relaxation time, seconds

   T1n_bulk - nuclear longitudinal relaxation time far away from the electron

   r        - electron-nuclear distance, Angstrom

   bet      - angle between the magnet field and the electron-nuclear direction, radians

Outputs

   R1n      - nuclear relaxation rate, Hz
