The scientists monitored the dreamers with both magneticresonance imaging and near-infrared spectroscopy to see patterns of heat in their subject's heads, which gives a picture of brain activity.
The structures of the above compounds were assigned by nuclear magneticresonance, mass spectrometry, and infrared spectroscopy etc.
以上所有化合物的结构通过核磁共振、质谱、红外光谱等确证。
