![]() 35Cl-NMR spectroscopy is mainly used to investigate ionic and inorganic chlorides. 10 7 rad T -1 s -1 Nuclear g-factor: g l = 0.5478 Quadrupole moment Q: - 0.08112 barn (100 fm 2) Resonance frequency: v 0 = 4.1765 at 1 T Frequency ratio: Ξ( 35Cl) = 9.797909 % Relative Sensitivity: 0.00472 (H 0 = const.) 0.4905 ( v 0 = const.) Reference compound: (conditions) sodium chloride solution with 0.1 M NaCl in deuterium oxide (line width 11.4 Hz).ģ5Cl, along with 37Cl is one of the two natural chlorine isotopes that are suitable for NMR spectroscopy ( 36Cl only occurs in trace amounts and is radioactive).Nuclear magnetic properties of the NMR active Nuclide 35Cl OccurrenceComparison of the natural Chlorine isotopes including isotopic abundance (mole fraction of the isotope mixture in percent): Name of the isotope: Chlorine-35 Cl-35 Symbol: 35Cl or 35 17Cl Mass number A: 35 (= number of nucleons) Atomic number Z: 17 (= number of protons) Neutrons N: 18 Isotopic mass: 34.9688527(3) u ( atomic weight of Chlorine-35) Nuclide mass: 34.959527 u (calculated nuclear mass without electrons) Mass excess: -29.01352 MeV Mass defect: 0.32014133200001 u (per nucleus) Nuclear binding energy: 298.20972991 MeV (per nucleus) 8.520278 MeV (average binding energy per nucleon) Separation energy: S N = 12.64476(5) MeV (first neutron) S P = 6.37081(4) MeV (first proton) Half-life: stable Spin and parity: (nuclear angular momentum) 3/2+ Magnetic dipole moment: μ(μ N) = +0.82170(2) Charge radius: 3.3654(191) femtometer fm Mirror nucleus: Argon-35 Year of discovery: 1919ĭirect parent isotopes are: 35Ar, 35S, 36K.
