I. Reading Exercises:

Exercise 1. Read and memorize using a dictionary:

derivatives, bulk properties, electrical conductivity, melting point, solubility, acidity, quantum theory, tools, solids, measurements, photoelectron spectrum, two-electron bonds, ionization process, insights, spectroscopy, paramagnetic species, light hydrogen nucleus, carbonyl ligands, cyclic voltammetry redox characteristics

Exercise 2. Answer the questions:

1) What encountered techniques do you know?

2) What can you say about the abilities of older methods of investigation?

3) What does electron-spin resonance allow?

4) What is the purpose of electrochemistry?

Exercise 3. Open brackets choosing the right words:

Such insights led to the (rejecting/popularization) of molecular orbital theory as (fully/partially) delocalized orbitals are a more appropriate simple (production/description) of electron removal and electron excitation.

II. Speaking Exercises:

Exercise 1. Describe quantum theory; X-ray crystallography; NMR spectroscopy; ultraviolet-visible spectroscopy; photoelectron spectrum using the suggected words and expressions as in example:

quantum theory

advent; expansion; new tools; to probe; solids; measurements; insights; theoretical models

example: With the advent of quantum theory and the corresponding expansion of electronic apparatus, new tools have been introduced to probe the electronic properties of inorganic molecules and solids. Often these measurements provide insights relevant to theoretical models.

X-ray crystallography

technique; determination; structure

NMR spectroscopy

nuclei; information; compound properties; paramagnetic species; proton; light hydrogen nucleus; detect

ultraviolet-visible spectroscopy

tool; inorganic compounds; to be colored

photoelectron spectrum

measurements; to demonstrate; two-electron bonds; carbon; hydrogen; ionization process

Exercise 2. Ask questions to the given answers:

1) Question: ___________________________________________ ?

Answer: Infrared spectroscopy is mostly used for absorptions from carbonyl ligands.

2) Question: ___________________________________________ ?

Answer: Because of the diverse range of elements and the correspondingly diverse properties of the resulting derivatives.

III. Writing Exercises:

Exercise 1. Compose a story on one of the topics (up to 40 words):

“Methods based on quantum theory”

“Forms of spectroscopy”

Exercise 2. Fill in the table with words and expressions from the text:
