NMR-Spectrometer 300 MHz for NMR on liquids

在KIT的仪器设备Pro2NMR中，它起源于DFG资助，核磁共振方法主要在工程问题的背景下开发和使用。研究了液态核磁共振和固态核磁共振以及弛豫和扩散，最终定名为核磁共振。200兆赫和400兆赫的频谱可供预订。它们配备了MRI所需的大磁场梯度，因此本提案要求专用的液体NMR。目前研究的问题是油的老化、聚合物网络中客体分子的扩散以及聚合物在溶液中的扩散。结晶化和顺磁弛豫增强也是实际的研究课题。计划中的硬件扩展将减少重新组织和转换仪器的需要，从而大大提高可用性，并大大减少错误和维修问题的数量。使用专用的硬件和软件，长期测量将再次成为可能。

In the instrumental facility Pro2NMR at KIT with its origin in a DFG funding, NMR methods are developed and used mainly in the context of engineering questions. Liquid and solid state NMR as well as relaxation and diffusion are explored, finally MRI is to be named. 200 MHz and 400 MHz spectrometers are available and completely booked. They are equipped with large magnetic field gradients needed for MRI, therefore a dedicated liquid NMR is asked for in this proposal. Currently addressed questions are aging of oils, diffusion of guest molecules in polymeric networks and of polymers in solution. Crystallization and paramagnetic relaxation enhancement are actual research topics, too. The planned hardware extension will reduce the need of reorganization and conversion of the instruments leading to a significantly enhanced usability and to a significantly reduced number of errors and repair issues. Long term measurements will be possible again using dedicated hard- and software.
