This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Relaxation is a summation of process by which magnetization decays over time. T1 and T2 are the characteristic parameters used to describe the process. The experiments are two series of HSQC mesurements modified so that the magnetization will remain on the nitrogen a different ammount of time in each measurement. T2 and T1 will be extracted by fitting a series of decline spctra in signal strength over relaxation time to a decreasing exponential.

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 弛豫是磁化强度随时间衰减的过程的总和。T1和T2是用于描述过程的特征参数。实验是两个系列的HSQC测量仪，其被修改为使得在每次测量中磁化将保持在氮上不同的时间量。T2和T1将通过将信号强度随弛豫时间的一系列下降谱拟合为递减指数来提取。
