Any dataset here, as the library's Tabulated material (chloroform/kedenburg-2012).

# ... load chcl3 as above, then:

    wavelengths=ls.WavelengthRange(start_nm=500, stop_nm=1000, num=81),
)
res = ls.solve(sim)  # exact Mie for a sphere
print(res.q_ext)     # extinction efficiency at each wavelength

Same spec runs with DDA, FDTD, BEM or T-matrix: ls.compare(sim, ["mie", "dda"]).

About CHCl3 (Chloroform)

Chloroform (CHCl₃) is a volatile, colorless, and sweet-smelling organic compound. Historically, it was used as an anesthetic; however, due to its potential health hazards and the development of safer alternatives, its use in this capacity has been discontinued. In modern applications, chloroform is predominantly used as a solvent in laboratories and in the production of the refrigerant freon. It is also a precursor in the manufacture of hydrochlorofluorocarbon (HCFC) refrigerants. When exposed to light and air, chloroform can undergo a reaction to produce phosgene, a highly toxic compound. Thus, commercial chloroform bottles typically contain stabilizers to prevent this reaction.
