· beam path = size of class
· inactive molecules = students not taking a piece
· quantitative = the number of absorbed pieces equals class size
· emission spectroscopy = the wrappers "emitted"
· transmittance = the number of pieces left
· multiphoton absorption = someone sneakily taking two pieces

In spectroscopy, we pass radiation with different frequencies through a sample of molecules to learn about molecular size/geometry. In this demonstration, I pass chocolate with different flavours through a class of students to learn about their chocolate preferences.

Now you can never pretend that you don't speak Swedish anymore! Well done 😊

Too ordered to be a solid solution! It is a superstructure
