Problem 19-16

In the cavity ring-down measurement at the opening of this chapter, absorbance is given by where L is the length of the cavity between mirrors, c is the speed of light, is the ring-down lifetime with sample in the cavity, and 0 is the ring-down lifetime with no sample in the cavity. Ring-down lifetime is obtained by fitting the observed ring-down signal intensity I to an exponential decay of the form I I0et/ , where I0 is the initial intensity and t is time. A measurement of CO2 is made at a wavelength absorbed by the molecule. The ring-down lifetime for a 21.0-cm-long empty cavity is 18.52 s and 16.06 s for a cavity containing CO2. Find the absorbance of CO2 at this wavelength. A

Chapter 2 Atoms and Elements 2.1 Imaging and Moving Individual Atoms  Scanning tunnel microscopy (STM) – A technique that can image (make a visual representation of), and even more, individual atoms & molecules. o Works by moving an extremely sharp electrode (a conductor through which electricity can enter or leave) over a surface and measuring the resulting tunneling current, the electrical current that flows between the tip of the electrode and the surface even though the two are no in physical contact.  Tunneling current is extremely sensitive to distance, making it possible to maintain a precise separation between the electrode tip and the surface by moving t
