Summary
Spin crossover (SCO) and light-induced excited spin state trapping (LIESST) effects in a coordination polymer were enforced by mechanical stimuli. This demonstrates manipulating spin states using multiple stimuli simultaneously.
Area of Science:
- Materials Science
- Solid-State Chemistry
- Coordination Polymers
Background:
- Spin crossover (SCO) and light-induced excited spin state trapping (LIESST) are crucial phenomena in materials science.
- Investigating these effects in coordination polymers can lead to novel functional materials.
Purpose of the Study:
- To investigate SCO and LIESST effects in a {[FeII(pyrazole)4]2[NbIV(CN)8]·4H2O} coordination polymer.
- To explore the possibility of enforcing these spin state transitions using external stimuli.
Main Methods:
- Single-crystal X-ray diffraction under high pressure and cryogenic temperatures.
- Application of mechanical stimuli to induce spin state changes.
Main Results:
- The {[FeII(pyrazole)4]2[NbIV(CN)8]·4H2O} coordination polymer did not exhibit SCO or LIESST at ambient pressure.
- These spin crossover and LIESST effects were successfully enforced by applying a mechanical stimulus.
- Demonstrated the manipulation of spin states through the simultaneous application of multiple stimuli.
Conclusions:
- Mechanical stimuli can enforce spin crossover and LIESST in specific coordination polymers.
- The study highlights the potential for controlling spin states via multi-stimuli responses in materials.

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

01:12Double Resonance Techniques: Overview
199
Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.

01:08NMR Spectroscopy: Spin–Spin Coupling
1.4K
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...

1.0K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

01:23Atomic Nuclei: Nuclear Relaxation Processes
649
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.

01:03Atomic Nuclei: Nuclear Spin State Overview
938
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of...
