Summary
We developed Spinach, a software library for efficient simulation of large spin systems. This enables complex nuclear magnetic resonance (NMR) and electron spin resonance (ESR) experiments on desktop computers.
Area of Science:
- Computational Chemistry
- Magnetic Resonance Spectroscopy
Background:
- Simulating large spin systems for magnetic resonance experiments is computationally intensive.
- Existing methods often struggle with systems exceeding 20 spins, limiting their applicability.
Purpose of the Study:
- To introduce a new software library, Spinach, for efficient simulation of large spin systems.
- To enable advanced Liouville space simulations of liquid-state NMR experiments on systems with over 40 spins.
Main Methods:
- Development of efficient simulation algorithms for large spin systems.
- Implementation of Liouville space simulations incorporating symmetry, relaxation, and chemical kinetics.
- Optimization for electron spin resonance (ESR), solid-state NMR, and spin chemistry simulations.
Main Results:
- Desktop workstation performance for liquid-state NMR experiments on 40+ spin systems.
- Significant improvements in the efficiency of ESR, solid-state NMR, and spin chemistry simulations.
- The Spinach software library is publicly available for download.
Conclusions:
- Spinach provides a powerful and accessible tool for researchers in magnetic resonance.
- The library facilitates complex simulations, advancing the study of spin dynamics.
- Enables broader application of advanced simulation techniques in various spectroscopic fields.

01:08Spin–Spin Coupling Constant: Overview
In bromoethane, the three methyl protons are coupled to the two methylene protons that are three bonds away. In accordance with the n+1 rule, the signal from the methyl protons is split into three peaks with 1:2:1 relative intensities. The methylene protons appear as a quartet, with the relative intensities of 1:3:3:1.
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must have a...

01:17Spin–Spin Coupling: One-Bond Coupling
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...
01:08NMR Spectroscopy: Spin–Spin Coupling
The spin state of an NMR-active nucleus can have a slight effect on its immediate electronic environment. This effect propagates through the intervening bonds and affects the electronic environments of NMR-active nuclei up to three bonds away; occasionally, even farther. This phenomenon is called spin–spin coupling or J-coupling. Coupling interactions are mutual and result in small changes in the absorption frequencies of both nuclei involved. While nuclei of the same element are involved in...
01:08Atomic Nuclei: Nuclear Spin
All atomic particles possess an intrinsic angular momentum, or 'spin'. Electrons, protons, and neutrons each have a spin value of ½, although protons and neutrons in nuclei may have higher half-integer spins owing to energetic factors.
Atomic nuclei have a net nuclear spin, , which can have an integer or half-integer value. In atomic nuclei, the spins of protons are paired against each other but not with neutrons, and vice versa. Consequently, an even number of protons does not contribute to...

01:14Atomic Nuclei: Nuclear Spin State Population Distribution
Near absolute zero temperatures, in the presence of a magnetic field, the majority of nuclei prefer the lower energy spin-up state to the higher energy spin-down state. As temperatures increase, the energy from thermal collisions distributes the spins more equally between the two states. The Boltzmann distribution equation gives the ratio of the number of spins predicted in the spin −½ (N−) and spin +½ (N+) states.
01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
