正则化分解变换（RRT）以一种新的方式应用于j分辨光谱。这包括直接计算45度投影，而不构建二维光谱。结果表明，即使对于更大的信号，也比2D傅里叶谱45度投影获得的分辨率有显著提高。特别是，RRT能够在非常拥挤的频谱区域中解析属于不同重叠多态的峰，而传统技术无法处理任何信号大小。该方法的分辨率高，所需信号短得多，使其成为频谱分配的有力工具。(C) 2003 Elsevier Science（美国）版权所有。
The regularized resolvent transform (RRT) has been applied in a novel way to J-resolved spectra. This involves the direct calculation of the 45degrees projection without constructing the 2D spectrum. The results show a significant resolution enhancement over that obtained by the 45degrees projection of a 2D Fourier spectrum, even for much larger signals. In particular, RRT is able to resolve peaks that belong to different overlapping multiplets in a very crowded spectral region, where the conventional technique fails for any signal size. The resolving power of this method along with the significantly shorter signals required, make this method a powerful tool in spectral assignment. (C) 2003 Elsevier Science (USA). All rights reserved.
