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.

在KIT的仪器设施Pro2NMR中，其起源于DFG资金，NMR方法主要在工程问题的背景下开发和使用。液态和固态核磁共振以及弛豫和扩散进行了探索，最后命名为MRI。200 MHz和400 MHz频谱仪可供使用，并已全部预订。它们配备了MRI所需的大磁场梯度，因此在本提案中要求使用专用液体NMR。目前解决的问题是老化的油，客体分子在聚合物网络和聚合物在溶液中的扩散。结晶和顺磁弛豫增强也是实际的研究课题。计划的硬件扩展将减少对仪器的重组和转换的需要，从而大大提高可用性，并大大减少错误和维修问题。使用专用的硬件和软件，长期测量将再次成为可能。
