FT-IR 谱分析仪产品说明书 Introduction The medicinal use of cannabis and cannabis-related products has experienced astronomical growth over the past decade. Canada, Germany,New Zealand and Columbia now have legal cannabis markets. In the United States,30 states plus the District of Columbia have ...
The classification criteria are presented as a table and illustrated by authentic FT-IR spectra obtained from MWL's. Peak-peaker lists of typical representatives of the three principal groups show the band intensities of normalized IR spectra. A triangular coordinate system...

Full size table The FT-IR pattern of peaks in the fingerprint region (400–1400 cm−1) and group frequency region (1400–4000 cm−1) is exclusive for each bond stretch. Here, we obtained the IR spectra from the test samples (banana flour, Bread) and compared the peak fingerprints wi...
The results indicated that the variati ons of abs or p ti on intensity of three characteristic bands,1600,3100-3200and 900-650cm-1,and the shift of abs or p ti on peak of1600c m-1can reflect the variati ons of ar omatizati on degree and carbon net constructi on of the charcoal....
Raman-Shift displays a peak at 1332 cm−1 attributed to the presence of diamond phase as shown in Fig. 4-a. Raman frequency of the laser beam concentrated on the substrate layer of the PDC cutter (tungsten-carbide layer) did not show any active peaks as shown in Fig. 4 (c). ...
