Experimental setup. a Schematic diagram of the simultaneous Raman/acoustic levitation system contained in a flow-through environmental chamber; b photograph of the online setup at MAX IV Laboratory with Raman probe (laser off) and levitated 80-μm droplet (inlay shows the microscopic image of a 80-μm droplet of our sample in the same levitator); c photograph of offline setup with 532-nm laser exciting Raman transitions in a large levitated droplet. Droplet locations in the photographs are highlighted by white arrows
