FT-Raman spectra were collected from fossil resins originating from a variety of geographical locations. The spectral profiles of most of the fossil resins could be related to modern resins containing diterpenoid components with predominantly labdane skeletons. The spectra collected from the fossil resin sample from Borneo differed from other fossil resins and was found to contain triterpenoid components. The differences in the spectral profile of fossil resins containing diterpenoid components are shown to relate to differences in level of maturation rather than geographical origin. FT-Raman spectra of fossil resins cannot be used to distinguish source although the degree of maturation can be used as an indicator to narrow the range of possible geographical origins.
傅里叶变换拉曼光谱是从来自不同地理位置的化石树脂中采集的。大多数化石树脂的光谱特征与含有主要为半日花烷骨架的二萜类成分的现代树脂有关。从婆罗洲的化石树脂样品中采集的光谱与其他化石树脂不同，并且发现含有三萜类成分。含有二萜类成分的化石树脂光谱特征的差异表明与成熟度水平的差异有关，而非地理来源。尽管成熟度可以作为缩小可能地理来源范围的指标，但化石树脂的傅里叶变换拉曼光谱不能用于区分来源。
