Functional molecules and macromolecules find applications in our everyday lives, from cosmetics to shampoo and cleaning products through to pharmaceutically active medicines and agrochemical pesticides. One of our roles as chemists is to understand how atoms are arranged and connected in these molecules. In this way, we can correlate the structure of a molecule directly to its properties; their subsequent application allows them to be incorporated into our everyday lives. One key technique used to study these molecules is liquid-state NMR spectroscopy. This technique is used to generate a detailed understanding of how the atoms are arranged in molecules, allowing us to understand how atomic arrangements change in chemical reactions. In turn, this allows us to build designer molecules for specific and selective purposes. This proposal will enable the purchase of a new liquid-state NMR spectrometer that will replace an obsolete and inefficient spectrometer. This new spectrometer will be part of the liquid-state NMR facility at St Andrews, giving us high sample throughput (typically over 75000 samples per year) and allowing us to study the connectivity of thousands of molecules. The new machine will be more sustainable than the older model, using less energy and coolants in normal use (estimated savings of £4 k per year) while improving research efficiency and productivity. Liquid-state NMR is a widely used technique in the physical sciences, directly supporting over 50% of the total researcher headcount in the School of Chemistry at the University of St Andrews. This facility will support the research of two early career researchers and a large number of PhD students (including those in the CRITICAT and EaSICAT doctoral training programmes) and post-doctoral researchers, in addition to over half of the established academics within the School.The vision is that this equipment will be an important step towards our goal of transforming the sustainability of our world-class facilities, thereby securing the instrumentation base necessary to allow us to continue to deliver world-leading research into the future. It will provide a core science facility that can be accessed by all researchers across the University to enhance the quality of science possible. The work that will be carried out will focus on a variety of systems of fundamental scientific interest as well as those with applications in pharmaceuticals, agrochemicals and healthcare.

功能分子和大分子在我们的日常生活中得到了应用，从化妆品到洗发水和清洁产品，再到药用活性药物和农用化学农药。作为化学家，我们的角色之一是了解原子在这些分子中是如何排列和连接的。通过这种方式，我们可以将分子结构与其性质直接联系起来；它们随后的应用使它们能够融入我们的日常生活。用于研究这些分子的一项关键技术是液态核磁共振波谱。这项技术被用来详细了解原子在分子中的排列方式，使我们能够了解原子排列在化学反应中是如何变化的。反过来，这使我们能够为特定和选择性的目的构建设计分子。这项提议将使人们能够购买一台新的液态核磁共振光谱仪，以取代过时和低效的光谱仪。这台新的光谱仪将是圣安德鲁斯的液态核磁共振设施的一部分，为我们提供高样品吞吐量(通常每年超过75000个样品)，并使我们能够研究数以千计的分子的连接性。新机器将比旧型号更可持续，在正常使用时使用更少的能源和冷却剂(估计每年节省4千GB)，同时提高研究效率和生产率。液态核磁共振是一种在物理科学中广泛使用的技术，直接支持圣安德鲁斯大学化学学院50%以上的研究人员。这一设施将支持两名早期职业研究人员和大量博士生(包括CRITICAT和EaSICAT博士培训计划中的那些人)和博士后研究人员的研究，以及学院内超过一半的现有学者。我们的愿景是，这一设备将是我们朝着改变我们世界级设施的可持续性的目标迈出的重要一步，从而确保必要的仪器基础，使我们能够继续在未来提供世界领先的研究。它将提供一个核心科学设施，整个大学的所有研究人员都可以使用，以尽可能提高科学的质量。将开展的工作将集中在具有基础科学意义的各种系统以及那些在制药、农用化学品和医疗保健中应用的系统。
