Band A4 has prominent P- and R-branches; this band is assigned to the CO-stretching mode coupled with the HCO bending (n4) mode of syn- CH3CHOO. The observed weak Q-branch arises from a small contribution of the n4 mode of anti-CH3CHOO. The contribu- tions of fundamental and hot ...
The valid strong THz absorption at 1.58 THz was probed in the organic-inorganic hybrid perovskite thin film, CH3NH3PbI3, fabricated by sequential vacuum evaporation method. In usual solution-based methods such as 2-step solution and antisolvent, we observed the relatively weak two main absorpti...
Can a solution with equal amounts of a strong base and its conjugate acid be used as a buffer? Explain why or why not. The compound methylamine is a weak base like ammonia. A solution contains 0.152 M CH3NH3+ and 0.296 M methylamine, CH3NH2. What is the pH of this ...
A salt produced from a weak acid and a strong base produces an acidic solution. This is because the conjugate acid of a weak base is a good acid. It acts as an acid by donating protons to the water molecules in the solution thereby producing hydronium ions. Answer and Explanation: Methy...
During those years [in the Moscow Conservatoire] my Sonatas and Partitas became stiff, monotonous and even more difficult to perform […] I used to play them with very little articulation, and without the distinction between strong and weak beats that is so naturally linked to bow-strokes. But...

Weak associations between COand I, COand HO, and Iand Ican account for shifts in their respective distribution coefficients, but these associations are not strong enough to produce isolable phases. The occurrence of a weak CO.HO molecular species in the vapor is demonstrated by the near-...
Hence due to reduced dielectric constant and increase width of the quantum well region the overall dielectric and quantum confinement effect is weak which results in relatively smaller exciton binding energies. It must be noted that on comparison with the long carbon chain based organic (BA), the...
