この積分器21からの出力を記録計23で記録する。The principle of measurement is as follows. Scattered light from the sample element 31 is separated into spectra by a spectroscope 15, and this spectroscopic light is received by a photomultiplier tube 17. The spectroscope 15 is of variable resolution, and in this embodiment, it sequentially scans wavelengths from 300 to 900 nm with a certain resolution. Then, information indicating whether the wavelength is present at that time (in Fig. 1, Ss
) is output to the recorder 23 each time. The current corresponding to the received light is amplified by a current amplifier 19, and then averaged by an integrator 21 in synchronization with laser oscillation.
The output from this integrator 21 is recorded by a recorder 23.

ところにのみ鋭いスペクトルが現われることが分った。As is clear from FIGS. 2 and 3, the sample element 31
It was found that sharp spectra appeared only at a wavelength of 355 nm and a wavelength of 532 nm.

It can be seen that the organic compound according to the present invention has nonlinear optical properties.
尚、この発明の有機非線形光学材料は、大きなSHG!
発するが、これは結晶が反転対称中心を持たない構造と
なっているためであると考えられる。Incidentally, the organic nonlinear optical material of this invention has a large SHG!

期待出来る。In addition, in the above-mentioned example, n in general formula (1) is 3
Although the description is given for a substance where n is 3 or more, it is thought that the same characteristics as in the example will be exhibited with respect to a substance where n is 3 or more. Roughly speaking, when n is 14 or more, the molecules of this substance exhibit amphiphilic properties, and therefore, it can be expected that it will be suitable for thin film production by the Langmuir-Brosier-Cito method.
