Attributes (in package)

Go to Top
Attribute Type Multiplicity Description
abundance FloatRatio 0..1 Fractional natural abundance natural abundance (e.g. 0.015 for 1.5%).  
gyroMagneticRatio Float 0..1 Gyromagnetic ratio (in rad/Ts)  
halfLife PositiveFloat 0..1 Halflife of isotope, in seconds. The interpretation of the value depends on the value of halfLifeType  
halfLifeError PositiveFloat 0..1 Estimated Standard Deviation ('error') fo the halfLife  
halfLifeType HalfLifeType 1..1 Enumerated string, describing how to interpret the halfLife value. If the value is 'stable' the isotope does not decay. See DataType HalfLifeType for details  
magneticMoment Float 0..1 in multiples of the nuclear magneton.  
mass Float 0..1 Isotope mass (in atomic mass units).  
massNumber Int 1..1 Isotope number (mass number). E.g. 1 for proton, 2 for deuterium, 13 for 13C etc.  
quadrupoleMoment Float 0..1 in units of barns (10**-24cm**2)  
receptivity Float 0..1 Relative NMR receptivity. 1H receptivity set to 1.0  
spin Word 0..1 nuclear spin (e.g. 0, 1/2, 5, 7/2 ...)
