📚 AQA AS Chemistry Paper 2 Data Booklet (January 2018): IR Data, Key Constants and Exam Strategy | AQA AS 化学 Paper 2 数据手册(2018年1月):红外数据、关键常数与应考策略

The AQA AS Chemistry Paper 2 data booklet is a compact but powerful tool. It gives you the infrared absorption table, key physical constants and the periodic table. This article explains how to use the booklet effectively for the January 2018 AS Paper 2, focusing on infrared spectroscopy and physical calculations.

AQA AS 化学 Paper 2 数据手册是一份紧凑但强大的工具。它为你提供红外吸收表、关键物理常数和周期表。本文解释如何针对 2018 年 1 月的 AS Paper 2 有效使用该手册,重点放在红外光谱和物理计算上。


1. What the Data Booklet Contains | 数据手册包含什么

The AQA AS Chemistry Paper 2 data booklet is the same insert supplied across the AS and A-level Chemistry series. For Paper 2, you are given tables of infrared absorption data, key physical constants, and a periodic table. Although the booklet also contains NMR data for A-level candidates, AS Paper 2 questions focus mainly on infrared spectroscopy and physical calculations.

AQA AS 化学 Paper 2 数据手册与 AS/A-level 化学各考季提供的插页相同。对于 Paper 2,你会获得红外吸收数据表、关键物理常数和周期表。虽然手册也包含 A-level 考生使用的核磁共振数据,但 AS Paper 2 题目主要集中在红外光谱和物理计算上。


2. Why the Data Booklet Is Not a ‘Cheat Sheet’ | 为什么数据手册不是“作弊纸”

The data booklet is not a shortcut to marks. It tells you the facts, but you must decide which data to use, interpret the spectrum, and link the data to the functional group. Many candidates lose marks because they copy a range from the booklet without explaining the evidence.

数据手册并不是得分的捷径。它给出事实,但你必须判断使用哪项数据、解释光谱,并把数据与官能团联系起来。许多考生失分是因为他们只从手册中抄下一个范围,却没有解释证据。


3. Infrared Spectroscopy: The Core Table for AS Paper 2 | 红外光谱:AS Paper 2 核心表

The most important table for AS Paper 2 is the infrared absorption table. It lists characteristic bond vibrations and their wavenumber ranges in cm⁻¹. You should know the main functional group absorptions even before opening the booklet, so that you can use the table quickly for confirmation.

AS Paper 2 最重要的表是红外吸收表。它列出了特征键振动及其波数范围(单位 cm⁻¹)。你应该在打开手册前就熟悉主要官能团的吸收,这样才能快速使用表格进行确认。

Bond / 键 Functional group / 官能团 Wavenumber / cm⁻¹ Peak shape / 峰形
O–H alcohols, phenols / 醇、酚 3200–3550 broad / 宽
O–H carboxylic acids / 羧酸 2500–3000 very broad / 非常宽
C–H alkanes, alkenes, arenes / 烷、烯、芳烃 2850–3300 medium–strong / 中–强
C=C alkenes / 烯烃 1620–1680 weak–medium / 弱–中
C=O aldehydes, ketones, carboxylic acids, esters, amides / 醛、酮、羧酸、酯、酰胺 1680–1750 strong / 强
C–O alcohols, esters, carboxylic acids / 醇、酯、羧酸 1000–1300 更多咨询请联系16621398022(同微信)
