    • 1C. For one pulse sequence only 1/√2 times signal is obtainable but 5/3 times pulse sequences can be repeated for the same time as used for the measurement by the 90° pulse sequence. Since (1/√2) × (5/3) times signal is obtainable and the noise decreases by √3/5 times (the noise is thought to decrease proportionally to the reciprocal square root of the repetition number of the measurements), a spectrum with larger signal/noise ratios is obtainable in the same measuring time.

    • The weak resonance observed in the range 14-15 ppm can be assigned to the methyl groups of the ends in the main chain. This resonance, however, is not pertinent to our present analysis.
