在过去的十年中,二维红外(2D IR)光谱已被证明是红外光谱的一个非常有用的扩展,但由于其实验复杂性和高昂的设备成本,该技术仍然局限于一小群专业研究人员。我们报告的光谱仪是紧凑的,机械鲁棒性,是比以前的设计便宜得多,因为它使用一个单像素的MCT检测器,而不是一个阵列检测器。此外,可以通过计算机编程在时域或频域中收集频谱的每个轴。我们讨论脉冲序列扫描探头轴,这是以前不可能的。我们给出了5 μm处金属羰基化合物和6 μm处模型肽的光谱。使用单像素MCT的数据收集比使用阵列探测器需要更长的时间,但是仅用几分钟的平均就可以获得可重复的质量数据。
Over the last decade two-dimensional infrared (2D IR) spectroscopy has proven to be a very useful extension of infrared spectroscopy, yet the technique remains restricted to a small group of specialized researchers because of its experimental complexity and high equipment cost. We report on a spectrometer that is compact, mechanically robust, and is much less expensive than previous designs because it uses a single pixel MCT detector rather than an array detector. Moreover, each axis of the spectrum can be collected in either the time or frequency domain via computer programming. We discuss pulse sequences for scanning the probe axis, which were not previously possible. We present spectra on metal carbonyl compounds at 5 µm and a model peptide at 6 µm. Data collection with a single pixel MCT takes longer than using an array detector, but publishable quality data are still achieved with only a few minutes of averaging.
