700 MHz NMR spectrometer with cryoprobe technique

A 700 MHz NMR spectrometer with cryoprobe technique is requested here. The focus of the samples to be measured has shifted in recent years from homogeneous catalysis to organic materials. This is particularly evident in SFB 1249 "N-heteropolycycles as functional materials", the excellence cluster "3D Matter Made to Order" and the Center for Advanced Materials. The samples are predominantly N-heteropolycyclic aromatic hydrocarbons or porous cage molecules. Due to the low dispersion of the signals, these molecules require the highest possible resolution and, because of the usually very low solubility, also the highest possible sensitivity. With the research networks, the number of users has also risen sharply. The increased demand for high-performance, high-field NMR measurements can no longer be met by the available NMR spectrometers. The requested device should fix the long waiting times for this
