Накратко на български

Ядрено-магнитната оптична спектроскопия изследва структурата на молекулите чрез измерване на специфични физични ефекти, като например оптичното въртене, предизвикано от ядрения спин. Новите методи позволяват по-висока разделителна способност и допълнителна информация за материали в хранителната и фармацевтичната индустрия.

Experimental Nuclear Magneto-Optic Spectroscopy

The field of spectroscopy offers methods for investigating structure of molecules and materials. It is an indispensable tool for discovering new molecules, exploring materials with novel properties, and assuring quality of the products in industries ranging from food through manufacturing of pharmaceuticals to the material engineering. Spectroscopy encompasses a wide range of methods. In this project, we have targeted at development of new spectroscopic techniques, which would allow to extend the possibilities of studies of molecules with very high resolution. These so-called nuclear magneto-optic spectroscopy (NMOS) methods are based on new physical phenomena, providing an insight into structure from a different angle than other methods and offering new, complementary information to other spectroscopies. So far, only one of the NMOS effects (nuclear spin-induced optical rotation - NSOR) has been measured, and only in three laboratories in the world, all based in USA. Our goal in this project were to construct a new instrument that would allow us to measure not only the so-far observed NSOR effect, but also other NMOS phenomena. We have successfully achieved the construction of the instrument that is capable of measuring the NSOR, making it the first such instrument in Europe. It is currently in principle capable of observing new NMOS effects as well with the experiments in development. The instrument itself is to be extended further in order to increase its versatility and provide access to more NMOS effects. Study of these new effects will open up a way to new spectroscopic techniques providing never before seen insight into the molecular structure of matter.

Цел на проекта

This project aims at building a world-unique instrument for measuring novel nuclear magneto-optic spectroscopy (NMOS) phenomena. In NMOS, the differential optical response to polarized nuclear spins is probed. The project aims at observing effects both in the dispersive spectral range, such as Nuclear Spin-induced Cotton-Mouton effect in strong magnetic field (NSCM-B) and Nuclear Quadrupole-induced Cotton-Mouton effect (NQCM), as well as phenomena in the absorptive range such as Nuclear Spin-induced Circular Dichroism (NSCD). The possibility to measure the nuclear magneto-optic effects both in and out of optical resonance, in both Faraday and Voigt geometries and by using either thermal nuclear spin polarization or the more sensitive induced hyperpolarization, offers an advantage over the already established set-ups.The results obtained using the constructed apparatus will serve to prove the existing theoretical predictions of the NMOS phenomena. The ultimate goals are the observation and measurement of the novel NMOS effects as well as the assessment of their ability to resolve chemically different nuclear sites via nucleus-specific response. The proposed techniques offer advantages such as the ability to focus on a particular functional group and to gain local high-resolution information, the use of optical detection and thus, increased sensitivity and resolution over the (in principle) similar Nuclear Magnetic Resonance (NMR). Additionally, NMOS will provide access to new physical observables offering different kinds of localized information than conventional NMR.These achievements will in the future have a potential for opening a wide array of applications of the NMOS effects as high-resolution analytical spectroscopic techniques in molecular and materials research, with prospects to be used in molecular and life sciences and on the industrial scale.
