Measurement of Quantitative IR Properties of Single Aerosol Particles with Emphasis on Biological and Chemical Stimulants
ABSTRACT
A simplified experiment in the visible range using 2 wavelengths (one in the absorption band and the other outside the
absorption band) was performed initially.We then shifted to the mid-IR (3.41 micrometers) using a mixture of H2O and D2O,
with the latter being the absorber. Again the peak-to-valley ratio increased upon the addition of D2O into H2O. The angular
distribution was collected on the backward scattering direction using an ellipsoidal mirror. The scattered light angle spanned
from 0 deg less than or equal to phi less than or equal to 360 deg and 90 deg less than or equal to theta less than or equal
to 163 deg.
