摘要： A process for producing 3,4-dihydrocoumarin comprising cyclization and dehydrogenation of a 3-(2-cyclohexanoyl)propionic acid ester, in which a reaction mixture obtained by the cyclization and dehydrogenation is washed with an alkali to reduce the dihydrocinnamic acid content of the reaction mixture to 1% by weight or less and/or previously distilling the reaction mixture to remove high-boiling substances, and then subjected to rectification to recover 3,4-dihydrocoumarin. The thus obtained 3,4-dihydrocoumarin has high purity and high quality sufficient for use as a perfume as it is.

摘要： In a method for generating a terahertz electromagnetic wave by using coherent phonons in a quantum structure, high density of coherent phonons acting as a radiation source of the terahertz electromagnetic wave are obtained by exciting the inter-band transitions in a quantum structure under the condition that the energy difference between two inter-band transitions in the quantum structure is resonated with the energy of the coherent phonons, and the terahertz electromagnetic wave is generated by the oscillatory polarizations of the coherent phonons. High density of coherent phonons may be created through the elementary excitation generated by using instantaneous laser pulses. A quantum well structure is effective as the quantum structure, and a scattering process of coherent phonon may be suppressed by confining coherent LO phonons in a well layer. Under the condition that the difference of energies between the heavy-hole and light-hole exitons in a quantum well structure agrees with the energy of LO phonons and both the exitons are created simultaneously, high density of coherent phonons may be generated. With this method, a terahertz electromagnetic wave can be effectively and strongly emitted from the coherent phonons.
摘要翻译：在通过在量子结构中使用相干声子来产生太赫兹电磁波的方法中，通过在量子结构中激发带间跃迁来获得充当太赫兹电磁波的辐射源的高密度相干声子，量子结构中的两个带间跃迁之间的能量差异与相干声子的能量共振，并且太赫兹电磁波由相干声子的振荡极化产生。可以通过使用瞬时激光脉冲产生的基本激发来产生高密度的相干声子。量子阱结构作为量子结构是有效的，并且可以通过将相干LO声子限定在阱层中来抑制相干声子的散射过程。在量子阱结构中的重孔和光空穴之间的能量差异与LO声子的能量一致并且两者同时产生的条件下，可能产生高密度的相干声子。通过这种方法，可以从相干声子有效强地发射太赫兹电磁波。
