複選題26. Which of the following statements correctly describe the rotational spectral activity of the listed molecules in microwave and rotational Raman spectroscopy, based on selection rules? (A) CH₄ shows rotational P/R branches in microwave spectroscopy because of its symmetric tetrahedral structure. (B) O₂ is both microwave and rotational Raman active because its symmetric stretch changes. (C) HBr is active in microwave spectroscopy because it is a heteronuclear diatomic molecule. (D) N₂ is microwave inactive but rotational Raman active. (E) CO₂ can show rotational Raman spectra but is microwave inactive due to its linear and centrosymmetric structure.

複選題25. Which of the following statements correctly describe the IR and vibrational Raman activity of the listed molecules based on vibrational selection rules? (A) CO₂ has both IR-active and Raman-active vibrational modes. (B) H₂O shows IR activity because its vibrations involve changes in dipole moment. (C) N₂ is IR active because it has a symmetric stretch that changes the molecule’s dipole moment. (D) CH₄ doesn’t exhibit Raman-active modes. (E) O₂ is Raman active but IR inactive.

複選題24. Which of the following statements about the use of Fourier Transform in spectroscopy are correct? (A) Fourier Transform is not applicable to nuclear magnetic resonance (NMR) spectroscopy because NMR data is already in the frequency domain. (B) In FTIR spectroscopy, a moving mirror is used in a Michelson interferometer to generate an interferogram from the incoming light. (C) Fourier Transform Infrared (FTIR) spectroscopy uses an interferometer to collect time-domain (interferogram) data, which is then converted to a frequency-domain spectrum. (D) Fourier Transform allows simultaneous measurement of all wavelengths, improving signal-to-noise ratio. (E) The signal-to-noise ratio is irrelevant to the number of measurements. 注意:背面有誤 台灣聯合大學系統115學年度碩士班招生考試試題 類組:化學類 科目:分析化學(1005) 共 6 頁 第 6 頁
