在甘油-水混合物(3：1)(半径约为12.44微米)的光学悬浮微滴的缓慢蒸发过程中，在其拉曼光谱中观察到了几个与形态有关的输入共振。这些共振在微滴中产生约10°C的突然温度跳跃，输出(拉曼)共振光谱的突然移动证明了这一点。后一种效应可以用简单的能量平衡计算和液滴折射率和密度对温度的依赖关系来解释。
During the slow evaporation of an optically levitated microdroplet of a glycerol-water mixture (3:1) (approximately 12.44 µm in radius) several morphology-dependent input resonances have been observed in its Raman spectrum. These resonances yield sudden temperature jumps of approximately 10 °C in the microdroplet as evidenced by sudden shifts in the output (Raman) resonance spectra. The latter effects could be explained by a simple energy balance calculation and the dependence of droplet refractive index and density on temperature.
