FTIR fingerprint spectra of various intact lichen samples (Dataset related to article)

Dataset related to the article "Chemically diverse: Chemotaxonomic discrimination and comparative fingerprinting of intact lichens from different families and genera using Fourier transform infrared (FTIR) spectroscopy and chemometrics" https://doi.org/10.1016/j.saa.2025.127260 The FTIR fingerprint spectra of intact lichen samples included in the related study discriminating lichens based on spectral patterns. The spectral data were deposited in JCAMP-DX format, which is widely recognized by many spectroscopy softwares. The data with prefix "Fig.1-2" are representative spectra that were used to create Figures 1 and 2 in the paper. All other spectra with abrreviated species codes (see the Table S1 in the related paper, also provided in this entry as a pdf file) were used in chemometric analyses for classification. All the spectra were recorded using an FTIR instrument operating in the mid-IR region and equipped with an attenuated total reflectance (ATR) cell.本数据集关联论文《化学多样性：利用傅里叶变换红外（Fourier Transform Infrared, FTIR）光谱法与化学计量学对不同科属地衣进行化学分类鉴别与比较指纹图谱分析》，对应DOI为https://doi.org/10.1016/j.saa.2025.127260。 相关研究中的完整地衣样本的傅里叶变换红外指纹光谱，可基于光谱模式对地衣实现分类鉴别。该光谱数据以JCAMP-DX格式存储，该格式已被多款主流光谱分析软件广泛认可。 前缀为"Fig.1-2"的光谱为代表性光谱，用于制作论文中的图1与图2。其余所有带有简化物种代码的光谱（详见相关论文中的表S1，本数据集条目也同步提供了该表格的PDF文件）均被用于化学计量学分类分析。 所有光谱均通过工作于中红外区域且配备衰减全反射（Attenuated Total Reflectance, ATR）样品池的傅里叶变换红外光谱仪采集获得。
